Technical Field

The present invention relates to an electric permanent wave treatment method capable of suppressing damage to hair, reducing a wavy wet/dry difference, shortening a restraint time of a technician, and improving work efficiency in a hair salon.

Background

The applicant has proposed, in patent document 1, an electric permanent wave treatment method capable of maintaining an initial wave close to a beam diameter for a long period of time. This is an invention in which after a treatment by a first agent of electric permanent wave, intermediate washing is performed to stop the progress of open chains of disulfide bonds, and then the hair is aligned in a state suitable for rearrangement of molecules (polymer movement), and thereafter, the hair is transferred to a dry state, and the second agent of electric permanent wave is used to perform a treatment to recombine disulfide bonds, thereby forming a desired wavy shape.

Specifically, the electric hair waving treatment method includes a first step of winding hair around a plurality of bars; a second step of applying a first agent for electric permanent wave containing a reducing agent to the wound hair to swell and soften the hair; a third step of rinsing the first permanent wave preparation adhered to the swollen and softened hair, or stopping the action of the first permanent wave preparation by an intermediate treatment agent for neutralizing the first permanent wave preparation, or performing both of them; a fourth step of, after the third step, covering the head of the person to be treated with the electric hair-perming treatment device with a cover, and maintaining the hair in a wet state while driving the hair dryer to warm the hair, or maintaining the inside of the shaft in a negative pressure state while driving the hair dryer in a weak state while covering the entire back head with a cover cloth from the forehead of the person to be treated with the electric hair-perming treatment device; a fifth step of drying the hair by driving the blower in a strong state and setting the inside of the bar in a negative pressure state after the fourth step; and a sixth step of drying the hair, applying a second agent for electric permanent wave containing an oxidizing agent, allowing the second agent to stand for a certain period of time, allowing disulfide bonds to recombine, and storing the hair in a dried shape.

Problems to be solved by the invention

However, when the invention proposed in patent document 1 is carried out, in the step of setting the hair in a state suitable for the rearrangement of the molecules, the step of drying the hair, and the subsequent step of the treatment with the second agent for electric permanent wave, since the same posture is forced on the hairdresser's chair, there is a concern that the burden on the person to be skilled in the art is large. In addition, in the process of performing treatment with the second electric permanent wave agent, the operator is limited to one skilled in the art, and cannot perform other operations in parallel, so that the efficiency of the operation in the hair salon is low, and there is a demand for improvement. Since the second agent for electric permanent wave is an aqueous solution, there are also problems as follows: in a wet environment, the re-bonding of disulfide bonds progresses in a direction to weaken the shape of hair formed in the drying step, and when the hair is dried, a wet/dry difference such as a difference in wave shape is generated.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an electric hair waving treatment method capable of reducing a wet/dry difference in a wavy shape, shortening a time for a technician to perform restraint, improving work efficiency in a hair shop, reducing a burden on the technician to be performed, and suppressing damage to hair.

Means for solving the problems

In order to achieve the above object, the present invention provides a method for electric permanent wave treatment, comprising applying a first agent for electric permanent wave having a reducing action to swell and soften hair wound around a shaft, rinsing the first agent for electric permanent wave, applying 1 or 2 or more compounds selected from the group consisting of ascorbic acid, ascorbic acid derivatives and ascorbic acid salts and an intermediate treatment agent to the hair, and thereafter, spraying ozone to the hair to oxidize the compounds, whereby the oxidized compounds and the ozone recombine disulfide bonds of the hair.

Further, in the electric permanent wave treatment method, it is preferable that the intermediate treatment agent contains the compound at a concentration of 0.13 to 24 wt%, and ozone atmosphere is formed by the ozone at 1.0ppm or less.

In particular, it is more preferable that the compound is fixed to the hair wound around the bar while heating the hair for a predetermined time to reunite the disulfide bonds of the hair, and the hair is kept moist, and thereafter the inside of the bar is brought into a negative pressure state, and ozone is sprayed to the hair while the hair is dried by a blower, thereby enclosing the hair with an ozone atmosphere.

In the present invention, the oxidized compound is dehydroascorbic acid or a salt of dehydroascorbic acid.

In the electric permanent wave treatment method, a second agent for electric permanent wave having an oxidizing action is applied to the hair in which the disulfide bonds are recombined, and the disulfide bonds are further recombined.

In the electric hair waving treatment method according to the present invention, 1 or 2 or more compounds selected from the group consisting of ascorbic acid, ascorbic acid derivatives and salts of ascorbic acid and an intermediate treatment agent are applied to hair, and thereafter ozone is sprayed to the hair to oxidize the compounds, whereby the oxidized compounds and ozone recombine disulfide bonds of the hair. Therefore, under the dry environment of ozone, the oxidized compound and ozone can reunite the disulfide bonds of the hair, and the problem of the difference between the wet and dry conditions caused by the technical process and the wave shape when the hair is dry can be solved. Since the oxidizing action is more favorably exerted by using the oxidized compound and ozone in combination, an electric permanent wave which is excellent in finishing can be formed. Furthermore, since disulfide bonds are recombined in a dry environment, the combing component of the intermediate treatment agent can be sufficiently impregnated into the hair. If a compound such as ascorbic acid applied to hair together with an intermediate treatment agent is oxidized by ozone, it becomes dehydroascorbic acid or a salt of dehydroascorbic acid, and they immediately exert an oxidizing action there, and therefore, it is effective for the formation of a finished good electric permanent wave.

In addition, since the technique of applying the second electric permanent wave agent and leaving the second electric permanent wave agent for a certain period of time is not required, the operator can be relieved from the restriction, the working efficiency in the hair salon can be improved, the overall time for applying the technique can be shortened, and the burden on the operator can be greatly reduced. Since the oxidation effect of the hair by ozone and the oxidized compound is immediately exerted, the damage of the hair which may be caused by the residual oxidation can be reduced. Since the compound such as ascorbic acid exerts a micro-reducing action when the intermediate treatment agent is applied, the drying/oxidation process can be started without inhibiting the molecular rearrangement of the hair.

In the present invention, a more satisfactory electric permanent wave can be formed by including the compound in the intermediate treatment agent so that the concentration thereof is 0.13 to 24% by weight and ozone is contained in an atmosphere of 1.0ppm or less of ozone. Further, since the oxidation effect can be obtained efficiently under the above parameters of the compound and ozone, the amount of ozone required for the recombination of disulfide bonds can be reduced. By reducing the amount of ozone, the safety and comfort of the operator and the person to be operated can be ensured, and the safety and comfort of the operator can be improved.

In the present invention, when the disulfide bonds of the hair are recombined, the compound is fixed to the hair wound around the shaft while the hair is heated for a predetermined time, and the hair is kept moist. Therefore, the oxidation action of dehydroascorbic acid or a salt thereof, which is a compound oxidized by ozone, can be effectively imparted to the hair wound around the shaft. If the oxidation action by the oxidized compound is effectively exerted, the amount of ozone can be reduced more and more. At the same time, the hair can be arranged in a state suitable for rearrangement of molecules (polymer movement). Further, in the present invention, the inside of the lever is brought into a negative pressure state, and ozone is sprayed to the hair while drying by the blower, so that the hair is surrounded by the ozone atmosphere. Therefore, the compound and ozone can be efficiently brought into contact with the hair wound around the shaft, and the disulfide bonds can be reliably recombined in a dry environment, thereby further eliminating the difference in moisture/dryness. By surrounding the hair with an ozone atmosphere, the oxidation can be uniformly applied to the entire hair, and the unevenness in the color tone of the final product can be suppressed.

In addition, in the present invention, the second agent for electric permanent wave having an oxidizing action can be applied to the hair in which disulfide bonds are recombined by the oxidized compound and ozone, and the disulfide bonds can be further recombined. The application technology of the second agent for electric perm can be finished in a very short time of 1-3 minutes. In addition, this process can be included in the combing operation performed at the shampooing station, requiring substantially no processing time. By applying the second agent for electric permanent wave to hair in which disulfide bonds are recombined by the oxidized compound and ozone, unevenness in the final color can be further suppressed.

Detailed Description

Hereinafter, the electric permanent wave treatment method according to the present invention will be described in detail. The embodiments described below are 1 example of embodying the present invention, and are not inventions limited thereto. The present invention can be modified in various ways without departing from the scope of the claims.

The present invention relates to a method of applying an electric permanent wave treatment, which comprises applying a first agent for electric permanent wave having a reducing action, swelling and softening hair wound around a bar, rinsing the first agent for electric permanent wave, applying an intermediate treatment agent, and thereafter, recombining disulfide bonds of the hair. The intermediate treatment agent contains 0.13-24 wt% (0.01-1.87M) of 1 or more than 2 compounds selected from the group consisting of ascorbic acid, ascorbic acid derivatives and ascorbic acid salts. Further, the 1 or 2 or more compounds selected from the group consisting of ascorbic acid, ascorbic acid derivatives and ascorbic acid salts may be adjusted to 0.13 to 24% by weight of the intermediate treatment agent in advance in a hair salon, for example, without being contained in the intermediate treatment agent itself. In this case, a method of applying the compound adjusted in advance to the hair and further applying the intermediate treatment agent to the hair can be proposed.

When the disulfide bonds of the hair are recombined, an ozone atmosphere of 1.0ppm or less is formed, and ozone is sprayed to the hair. Ozone oxidizes 1 or 2 or more compounds selected from the group consisting of ascorbic acid, ascorbic acid derivatives, and salts of ascorbic acid, which have been applied to hair, and the oxidized compounds and ozone recombine disulfide bonds of hair. In particular, when the disulfide bonds of the hair are recombined, it takes a predetermined time (for example, 3 to 15 minutes) to heat the hair, and the compound such as ascorbic acid contained in the intermediate treatment agent is reliably fixed to the hair wound around the bar. At this time, the hair is maintained moist. Further, the inside of the bar is brought into a negative pressure state, and ozone is sprayed to the hair while drying by the blower to form an ozone atmosphere, whereby the entire hair is surrounded by ozone of a uniform concentration, and the compound and ozone are efficiently brought into contact with the hair wound around the bar.

In the present invention, under a dry environment such as an ozone atmosphere, the recombination of disulfide bonds by ozone and an oxidized compound (dehydroascorbic acid or the like) is performed. Therefore, the problem of the difference between wet and dry in the wave shape is solved in the conventional application process of applying the second agent for electric permanent wave in a wet environment and the final processing of drying the hair thereafter. Further, since the whole hair is surrounded by ozone of a uniform concentration by forming an ozone atmosphere, oxidation occurs uniformly over the whole hair, and unevenness in the color tone of the final hair perming is suppressed. When a compound such as ascorbic acid applied to hair together with an intermediate treatment agent is reliably fixed to hair wound on a bar, oxidation by ozone to dehydroascorbic acid or a salt of dehydroascorbic acid is caused, and the instability of the physical properties of the dehydroascorbic acid or the salt of dehydroascorbic acid exerts an oxidizing action thereon, so that the action effectively reaches the hair wound on the bar. That is, by using the oxidized compound and ozone in combination, the efficiency of the oxidation effect is improved, and the required amount of ozone (ozone concentration to be sprayed) is suppressed to be low.

Here, in the present invention, in order to further suppress the uneven color tone of the final wave-shaped workpiece, the following implementation technique may be added: a second agent for electric permanent wave having an oxidizing action is applied to the hair having the disulfide bonds recombined, thereby recombining the disulfide bonds. This technique can be completed in a very short time of 1 to 3 minutes. In particular, since the hair dressing technology is performed for the purpose of further suppressing the unevenness of the color tone of the final hair, the treatment time for applying the second electric permanent wave agent can be substantially zero in the combing operation performed at the hair washing station.

The concentration of 1 or 2 or more compounds selected from the group consisting of ascorbic acid, ascorbic acid derivatives and ascorbic acid salts is 0.01 to 1.87M (0.13 to 24 wt%) relative to the intermediate treatment agent. If the concentration is lower than 0.01M (0.13 wt%), even if dehydroascorbic acid or a salt of dehydroascorbic acid is produced by oxidation with ozone, it cannot be expected that the oxidation effect will be exerted on the hair, and therefore, this is not recommended. If the concentration is higher than 1.87M (24 wt%), the oxidation effect of ascorbic acid itself may be saturated, and problems such as bleaching action of ascorbic acid, texture of finished waves, and uneven color in the shape of waves may occur, and thus, this concentration is not recommended.

In addition, the reason why the concentration of ozone atmosphere formed by spraying ozone to hair is 1.0ppm or less is considered to be safety of ozone spraying to human body. The lower limit of the concentration of the ozone atmosphere is, for example, 0.05ppm, but it may be determined appropriately depending on the relationship with the final processing of the desired wave shape, color shading, and the like in the electric permanent wave treatment.

Examples

An embodiment of an electric permanent wave treatment method according to the present invention will be described below together with the accompanying drawings. This embodiment is implemented by using a new electric permanent wave treatment device constructed based on the creation of the present invention.

First, a new electric permanent wave treatment apparatus will be explained. As shown in fig. 1, the electric permanent wave treatment apparatus a is constituted by an apparatus main body 1, a cover 2, an ozone unit 3, and a chemical spray unit 4. The lower part is provided with a caster which is a movable structure.

The apparatus main body 1 is configured by accommodating a circulation type blower 12, a steam-water separator 13, and an outside air introducing device (not shown) in a casing 11, the circulation type blower 12 being configured by a motor and a fan, discharging warm air heated by a heater into the cover 2, sucking the warm air from the cover 2, and heating the warm air again by the heater; the steam separator 13 separates moisture contained therein, foreign substances generated during the electric permanent wave treatment, and the like from the warm air sucked by the blower 12, and introduces the outside air, mixes the introduced outside air with the warm air discharged into the hood 2, and cools the mixture.

The circulation type blower 12 discharges warm air into the hood 2 through a warm air discharge port (not shown) and a suction port 12a formed in the casing 11, and sucks the warm air from the hood 2. The warm air discharged into the cover 2 is sucked from the bar around which the hair is wound, through the pipe attached to the bar and the suction port 12a to which the pipe is attached. In addition, if the flow of the warm air in the cover 2 is considered, the warm air discharge port (not shown) and the suction port 12a are preferably configured as follows: in the upper part of the casing 11, suction ports 12a are formed in both side parts of the upper part of the casing 11, and a warm air discharge port is formed in a region sandwiched by the suction ports 12a in the upper part of the casing 11. In addition, it can be said that the warm air discharge port is preferably configured as follows in order to make the temperature inside the hood 2 uniform and further make the ozone concentration of the ozone atmosphere described later uniform: an area occupying a predetermined degree of the region sandwiched by the suction ports 12a (for example, an area 5 to 50 times as large as the suction ports 12 a) is formed in the upper portion of the housing 11.

In the casing 11, a branch port is provided in a pipe from the heater to the warm air outlet, and the pipe from the branch port is connected to the outside air introducing device. The outside air introducing device includes a fan, and the fan is driven to mix the outside air with the warm air through the branch port. An outside air intake port for taking outside air into the outside air introducing device is formed in a side surface of the casing 11. Further, the bar has a plurality of air flow holes formed in an outer peripheral surface thereof. The tube is connected to the bar and the suction port 12a, and when the tube is in a negative pressure state by suction of the blower 12, the bar is also in a negative pressure state.

The cover 2 is configured to be separated into two, i.e., a first cover 21 and a second cover 22 so as to be openable and closable. The first cover 21 and the second cover 22 are coupled to the upper portion of the housing 11 by a coupling portion. The first cover 21 can be rotated in a direction overlapping the second cover by the coupling portion. The second cover 22 is disposed on the other side of the first cover 21 and can be rotated in a direction overlapping the first cover 21 by the coupling portion. The shapes of the first cover 21 and the second cover 22 may be any shapes such as circular arc shapes, quadrilateral shapes, hexagonal shapes, and the like, which cover the head.

The ozone unit 3 is an ozone generating device that generates ozone from oxygen in the air by a discharge method, an ultraviolet method, or the like, and is provided at an upper portion of the housing 11. The ozone unit 3 is provided with an ozone outlet 31 having a tip end penetrating the first cover 21 and protruding into the cover 2, and capable of blowing the generated ozone into the cover 2. The ozone outlet 31 is disposed in the vicinity of the warm air outlet. The ozone outlet 31 may be formed in a circular shape as shown in fig. 1, a circular arc shape, a rectangular shape, a flat elliptical shape, or the like. Since the ozone blown out from the air outlet 31 is diffused into the hood 2 by the warm air discharged from the warm air outlet, the shape of the air outlet may be selected so that the ozone can efficiently follow the warm air.

That is, the ozone generated by the ozone unit 3 is blown out in a relatively wide area in the vicinity of the warm air outlet, and the ozone is efficiently blown out in accordance with the warm air to form an outlet shape of the ozone atmosphere having a uniform concentration in the hood 2. This diffusion state of ozone can make the inside of the hood 2 have a substantially uniform ozone atmosphere with a concentration of 1.0ppm or less. When the supply of ozone is stopped by ozone unit 3, ozone in cover 2 is decomposed by itself and disappears in a short time. The ozone atmosphere in the hood 2 can be adjusted to a suitable concentration by controlling the amount of ozone supplied from the ozone unit 3.

The chemical spraying unit 4 is constituted by a chemical spraying can 41, a chemical spraying member 42, a fan 43, and a chemical spraying opening driving motor 44, and the chemical spraying can 41 contains a chemical as an intermediate treatment agent including 1 or 2 or more compounds selected from the group consisting of ascorbic acid, an ascorbic acid derivative, and an ascorbic acid salt, and is provided with an atomizing mechanism for atomizing the chemical by ultrasonic waves or the like; the chemical spraying member 42 moves in the cover 2 to uniformly spray the chemical atomized by the chemical spraying can 41 to the hair; the fan 43 sends the atomized medicine from the medicine spraying can 41 to the medicine spraying component 42; the chemical spray opening driving motor 44 applies a driving force for reciprocating the chemical spray member 42 along the inner peripheral surface of the cover 2.

The chemical spraying member 42 is a curved tube corresponding to the inner shape of the cover 2, and has a plurality of spray outlets formed on the surface thereof. The chemical spray member 42 reciprocates along the inner peripheral surface of the cover 2, and is realized by incorporating a motor 44 for driving the chemical spray outlet into a coupling portion of the cover 2, attaching a gear to a rotary shaft thereof, and attaching a gear corresponding thereto to an end portion of the chemical spray member 42 as shown in fig. 1. Further, by providing the drug atomizing member 42 with a plurality of joints and the like, complicated movement along the inner peripheral surface of the cover 2 can be performed in addition to the reciprocating movement along the front-rear direction (the left-right direction in fig. 1) of the inner peripheral surface of the cover 2.

The chemical agent is an intermediate treatment agent as an acid pickling agent, and is composed of 0.13-24 wt% of 1 or more compounds selected from the group consisting of ascorbic acid, ascorbic acid derivatives, and ascorbic acid salts. The amount of spray can be adjusted appropriately according to the amount of hair to be treated by electric permanent wave, the texture of hard, soft hair, and the like. In the case where the intermediate treatment agent itself does not contain 1 or 2 or more compounds selected from the group consisting of ascorbic acid, ascorbic acid derivatives, and salts of ascorbic acid, the powder or the like of the compound is adjusted to 0.13 to 24 wt% based on the intermediate treatment agent in advance in a hair salon immediately before use, and then the agent spraying means 4 is operated to spray the intermediate treatment agent containing no compound to the hair.

Although not shown, the electric hair iron treatment device a includes a control unit having an operation display screen and a CPU for displaying time, temperature, the number of bars, the amount of hair, damage to hair, operation of the ozone-spraying device, and spraying of chemicals. The control unit is provided with setting buttons for performing the respective displays. Then, the operator operates the setting button to perform information processing by the CPU, thereby executing various controls in the electric hair iron processing apparatus a. Specifically, the ozone control setting button for controlling the ozone concentration level by controlling, for example, the current of the ozone unit 3, the chemical spray amount control setting button for controlling the chemical spray amount of the chemical spray unit 4, and the chemical spray port driving motor setting button for controlling the operation of the chemical spray member 42 reciprocating along the inner circumferential surface of the cover 2 are mainly provided with a lever number setting button for setting the number of levers for winding the hair of the person to be treated, a hair amount setting button for setting the amount of hair of the person to be treated, and a damage check setting button for setting the damage state of the hair of the person to be treated. When the technician operates the setting buttons, the data of the operating time and the operating temperature corresponding to the operating time and the operating temperature are stored in the ROM provided in the control unit, and the CPU of the control unit performs information processing. In addition, the technician can also store various settings in the RAM incorporated in the control unit as desired.

The control of the control unit by the setting button operation by the operator includes, for example, temperature control of the heater by a switch for turning on and off the energization of the heater, time control by a timer for calculating the time set by the ROM, on and off control of warm air, and blower control for adjusting the air volume. Further, a start switch for starting these controls is provided in the control unit. When a temperature sensor for detecting the temperature inside the cover 2 is provided in the cover 2, the control of the control unit includes the temperature control inside the cover 2, and a start switch for the temperature control is provided in the control unit. The control unit preferably includes, in addition to the above, a safety button or the like for turning off the power supply when an abnormality occurs. In the electric hair iron treatment apparatus a, a series of electric hair irons are performed by the operation of each switch by the operator.

Next, a series of electric permanent wave treatment methods using the electric permanent wave treatment device a will be described. Here, an example in which a salt of ascorbic acid is used is described as a compound contained in the intermediate treatment agent.

First, a person skilled in the art winds a bar around the hair of the person skilled in the art, applies a known first agent for electric permanent wave having a reducing action to the hair wound around the bar, and leaves the bar in this state for a predetermined time to swell and soften the hair. If it is confirmed that the hair is swollen and softened, the first dose of electric permanent wave attached to the hair is rinsed and wiped with a towel. Further, the person to be operated is seated on the electric hair wave treatment device A. At this time, it is convenient to open the cover 2 in advance by overlapping the first cover 21 and the second cover 22 by rotation. When the subject is seated, the first cover 21 and the second cover 22 are rotated to close the opened cover 2 and cover the head of the subject. The opening side of the second cover 22, which is in contact with the face side of the subject, is covered with cloth so as to prevent leakage of warm air, and the inside of the cover 2 is sealed. In this state, the operator operates the setting buttons of the electric permanent wave treatment device a to perform the electric permanent wave treatment method according to the present invention.

First, the medicine atomizing unit 4 is moved to uniformly spray the medicine to the entire hair while moving the medicine atomizing member 42 in the cover 2. In this case, the concentration of the ascorbic acid salt contained in the drug is determined as appropriate in relation to the ozone concentration in the ozone atmosphere described later, but 0.05 to 0.72M is reasonable, and 0.05 to 0.36M is recommended from the viewpoint of cost. By fixing the agent to the hair, a combing effect is exerted on the hair. In addition, the drying/oxidation process can be started without hindering the molecular rearrangement of the hair by the micro-reduction action of the ascorbic acid salt. The skilled person confirms whether or not the drug is fixed to the hair wound around the portion on the rear side of the bar with respect to the drug spraying means 42, and if it is considered that the spray color is uneven, fine adjustment is performed so that the drug is uniformly fixed to the entire hair by moving the drug spraying means 4 locally or manually.

Then, the hair is kept wet for a predetermined time (for example, about 3 to 15 minutes) controlled in accordance with the hardness, amount, and the like of the hair while being heated by the blower 12, thereby further fixing the drug in the hair wound around the bar. The blower 1 is controlled to discharge warm air of a controlled temperature and a controlled intensity (weak blower, strong blower, etc.), and the inside of the cover 2 becomes a constant temperature atmosphere. In this state, the hair is warmed to a predetermined temperature (preferably 60 degrees or less) and for a predetermined time (depending on the hardness of the hair, the amount of hair, and the like), and is thus arranged in a state suitable for the rearrangement of molecules in the hair (polymer migration).

The hair can also be warmed by heating the inside of the cover 2 with a steam or mist atmosphere by an appropriate means together with warm air generated by the blower 1. By heating with steam or mist, the moisture content and temperature of the hair in a wet state can be easily controlled within desired ranges, and the electric permanent wave treatment can be performed with less failure and with higher wave efficiency. The temperature control and the time control can be automated because various control units are incorporated in the electric hair iron treatment apparatus a as described above. Of course, the control for maintaining the hair moisturization may also be performed manually.

Thereafter, if the tube is connected to a bar wound around the hair and the tube is also connected to the suction port 12a, the inside of the bar is made negative in pressure by the blower 1, and ozone is sprayed from the ozone unit 3 into the cover 2 toward the hair, so that the whole hair is surrounded by the ozone atmosphere, and the disulfide bonds of the hair are recombined. Since warm air is discharged from a region occupying a relatively large area of the upper part of the housing by the blower 12 and the inside of the cover 2 is in a closed state, the entire hair is surrounded by ozone of a uniform concentration. In this case, the inside of the lever is made to have a negative pressure, so that the contact efficiency of ozone with hair can be improved, and the oxidation action can be effectively exerted. The sprayed ozone can form an ozone atmosphere of 1.0ppm or less in the mask 2, but can be appropriately adjusted in relation to the concentration of ascorbic acid or the like contained in the chemical.

In the cover 2, the ascorbic acid salt on the hair is oxidized by the ozone atmosphere to become dehydroascorbic acid salt, which exerts an oxidizing action and causes the re-bonding of disulfide bonds of the hair fixed thereto. Further, the re-bonding of disulfide bonds in the entire hair surrounded by the ozone atmosphere proceeds by the oxidation action of ozone itself. The re-bonding of the disulfide bonds of the hair is performed in a dry environment since the hair is dried by the blower 12. In addition, since oxidation is performed in an environment surrounded by an ozone atmosphere, the action is uniformly exerted on the entire hair.

Finally, the skilled person confirms that the whole hair is sufficiently dry, removes the bar from the hair, and confirms the final processing. Thereafter, the craftsman is groomed at the shampooing station. In this combing operation, in order to further suppress the shading unevenness of the final processed color, the disulfide bonds of the hair may be further recombined with a known second agent for electric permanent wave having an oxidizing effect applied to the hair in which the disulfide bonds are recombined. This implementation technique can be completed in a very short time of 1 to 3 minutes. In addition, since the application of such second agent for electric permanent wave is included in the combing, the treatment time is substantially zero. The application technique is finished by drying the hair to design the style.

Next, the present invention is described in detail in terms of excellence in the electric permanent wave treatment method proposed in the above-mentioned patent document 1.

In the permanent wave treatment method according to patent document 1, the hair is heated and dried before the disulfide bonds of the hair are recombined by the second agent for electric permanent wave, and the molecules in the hair are aligned in a state suitable for rearrangement (polymer migration), thereby improving the wave efficiency. However, since the disulfide bond recombination of the hair by the second agent for electric permanent wave is performed in a wet environment, there is a problem that the wet/dry difference in the wave shape is generated when the technical process is performed and the hair is dried. On the other hand, in the present invention, since the hair is heated and dried, the effect of improving the wave efficiency can be obtained as it is, and furthermore, since the disulfide bond of the hair is recombined in a dry environment by using dehydroascorbic acid or the like in combination with ozone, the problem of the difference between wet and dry can be successfully solved. Further, since the inside of the cover is sealed and the entire hair is surrounded by the ozone atmosphere, oxidation uniformly occurs over the entire hair, and the variation in the final color shade of the electric permanent wave is successfully suppressed. By using a salt of dehydroascorbic acid or the like in combination, the amount of ozone required for spraying (the concentration of ozone to be sprayed) can be suppressed to be low. In addition, by reducing the amount of ozone, the implementation of technical personnel and the implementation of technical personnel exposed to the concentration of ozone can be suppressed within the recommended concentration of the degree, ensure the implementation of technical personnel and the implementation of technical personnel safety, comfort, and improve the implementation of technical safety, comfort.

In particular, in the method of permanent wave treatment according to patent document 1, the same posture is forced on the hairdresser's chair in the step of heating the hair, the step of drying the hair, and the subsequent step of treatment with the second electric permanent wave agent, which results in a large burden on the skilled person. On the other hand, in the present invention, since the disulfide bonds of the hair are recombined in the step of heating the hair and the step of drying the hair, the step of treating with the second agent for electric permanent wave (the application time) can be substantially omitted, and the burden on the person to be subjected to the technique can be successfully reduced significantly. The operator is free from the constraint, and therefore can expect a dramatic improvement in the work efficiency in the hair salon.

In addition, in order to further suppress the shading unevenness of the finish color, a known second agent for electric permanent wave having an oxidizing effect is applied to the hair in which the disulfide bonds are recombined, and the disulfide bonds of the hair are recombined. That is, the electric hair waving treatment with good finishing was successfully carried out without lowering the working efficiency in the hair salon.

Next, the electric permanent wave treatment method described above will be described in addition to the treatment performed after the electric permanent wave treatment device a is operated, based on the flowcharts shown in fig. 2 to 4.

As shown in fig. 2, in the electric permanent wave treatment apparatus a, when a power switch for supplying an external ac power is turned on, the treatment is performed in the following mode: a program setting mode S1 for executing the program setting by the operator operating each setting button in the control part; a medicine spray pattern S2 of applying an intermediate treatment agent containing a compound to hair; a creep pattern S3 (drying step) for fixing a chemical (compound) and maintaining the hair wet; a vitrification mode S4 in which the oxidized compound and the disulfide bonds of the hair are recombined by ozone spraying (oxidation step); a sequence of cooling modes S5 for cooling the hair.

First, in the program setting mode S1, a technician operates each switch in the control unit to perform program setting. That is, various settings are made such as the number of bars (step S11), the damage level of the hair (step S12), and the amount of hair (step S13). Then, the control unit reads out the timer, the temperature, the blower output, the ozone concentration level, and the medicine spray amount including the operation of the medicine spray unit 42 corresponding to the operated condition from the ROM, and determines the modes thereof (step S14). The CPU incorporated in the control unit shifts to the medicine spray mode S2 shown in fig. 3, monitors whether or not the technician turns on the start switch for medicine spray (step S21), and if the technician turns on the start switch, starts the timer set in the program setting mode S1 (step S22).

When the timer is started in step S22, the electric hair iron treatment device a sprays the mist of chemical onto the hair in accordance with the controlled amount of sprayed chemical and the operation of the chemical spraying means 42 (step S23). In the program setting mode S1, the spray amount is set according to the amount of hair, damage, and the number of bars, and therefore the amount of the chemical adhering is also optimized.

Next, the CPU monitors whether or not the time of the timer of step S22 reaches the set time (step S24). If it is determined that the set time has been reached, the routine shifts to a creep mode S3 shown in fig. 4, and the technician monitors whether or not the start switch for creep is turned on (step S31), and if it is determined that the start switch is turned on, the timer set in the program setting S1 is started (step S32).

When the timer is started in step S32, the electric hair iron processing apparatus a drives the hair dryer 12 and the outside air introducing device at the same time, and thus blows warm air from the warm air outlet (step S33). The CPU starts heater control so that the temperature inside the cover 2 becomes constant, that is, warm air at the temperature set by the ROM (step S34). The temperature inside the cover 2 is monitored by a temperature sensor and controlled to a temperature set by the ROM (step S35). Next, the CPU determines whether or not the time of the timer set in the ROM reaches the set time (step S36), and if it is determined that the set time is reached, the process proceeds to the vitrification mode S4 shown in fig. 5.

The technician operates the start switch for vitrification after connecting the tube to the lever. Therefore, it is necessary to confirm the condition of connecting the pipe to the bar. On the other hand, as shown in fig. 5, the CPU monitors whether or not the technician turns on the start switch for vitrification (step S41), and if it is determined that the switch is turned on, the timer set in the program setting S1 is started (step S42). When the timer of step S42 is started, the electric hair iron treatment device a drives the blower 12 and the outside air introducing device again to blow out warm air and sucks the warm air through the bar with the hair curled up to bring the inside of the bar into a negative pressure state (step S43).

At the same time as the start of the operation of step S43, the electric permanent wave treatment device a discharges ozone from the ozone unit 3, so that the ozone is uniformly diffused into the hood 2 by the warm air at the warm air outlet of the blower 12 (step S44). Next, the CPU starts the control of the heater, monitors the temperature inside the cover 2 by the temperature sensor so that the temperature inside the cover 2 becomes constant (step S45), and controls the temperature to the temperature set by the ROM (step S46). Next, it is determined whether or not the time of the timer set in the ROM reaches the set time (step S47), and if it is determined that the time reaches the set time, the operation shifts to the cooling mode S5.

At this stage, since the inside of the lever 2 is already in a negative pressure state, the ozone supplied into the cover 2 is sucked through the hair, the hair is oxidized by its own oxidation action, and the salt of ascorbic acid contained in the agent applied to the hair is oxidized to be a salt of dehydroascorbic acid, whereby the salt of dehydroascorbic acid also oxidizes the hair to recombine the disulfide bonds of the hair.

When the operation mode shifts to the cooling mode S5, the CPU monitors whether or not the technician has operated the start switch for cooling (step S51), and when the CPU determines that the CPU is on, the timer set in the program setting S1 is started (step S52). At the same time as the start of the operation of step S52, the electric hair iron treatment device a drives the hair dryer 12 and the outside air introducing device (blocks the supply of electricity to the heater) to cool the hair by sucking cool air from the inside of the bar 2 around which the hair is wound or by blowing air (step S53).

Then, it is determined whether or not the time of the timer set in the ROM reaches the set time (step S54), and if it is determined that the set time is reached, the series of control by the control unit is ended. The technician opens the cover 2 and removes the bar from the hair, thereby completing the operation.

In the electric permanent wave treatment method, after the agent is sprayed to the hair, a creep treatment is performed. Therefore, since the tube is not connected to the bar, the medicine is not sucked from the bar wound around the hair. However, in the present invention, the treatment of blowing the chemical agent to the hair may be performed immediately before the vitrification treatment after the creep treatment.

In this case, since the tube is connected to the bar immediately before the vitrification process, the chemical is sprayed and then the inside of the bar 2 is brought into a negative pressure state, so that the atomized chemical is uniformly distributed to the entire hair wound around the bar by the negative pressure inside the bar and is efficiently fixed to the hair. In addition, since the inside of the lever is brought into a negative pressure state, warm air in the cover 2 is sucked and supplied to the hair, and the finishing quality is improved.

In addition, when the tube is connected to the lever at the time of spraying the chemical agent, the inside of the lever is brought into a negative pressure state, whereby the chemical agent can be uniformly spread over the entire hair and can be efficiently fixed to the hair. In this case, since the inside of the lever is in a negative pressure state in the creep process as the next step, the warm air in the cover 2 is sucked and the warm air is supplied to the hair, and the finishing quality is improved.
