Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a comb used as an instrument for performing a straightening operation, that is, a straightening operation for curly hair, and its effective use. A comb that can be performed without damaging the hair and that does not hurt the hair, improves the finish of the hair after the treatment, and the durability of the hair straightening effect, and a comb that is extremely useful for improving the hair, and a convenient and effective use of the comb. On how to do.

[0002]

2. Description of the Related Art In a method of using a two-bath type straightening agent which is a typical straightening method at present, a first agent containing a reducing agent such as thioglycolate is first applied to the hair. After cutting the disulfide bond of the tissue, the first hair is stretched in a state where the tissue is swollen and plasticized, and then the hair is washed with water or hot water, and then the first step containing an oxidizing agent such as sodium bromate is performed. Apply the two agents to the hair and leave it for a second time, and then in that state, perform the operation of stretching the hair a second time, and then leave it for the first time.
The disulfide bond of the hair tissue cut by the agent is regenerated to straighten the curly hair.

Thus, the intervention of the operation of stretching the hair is necessary for the straightening method, and a panel has been conventionally used as an instrument for stretching the hair, but nowadays due to the frequent occurrence of hair cutting accidents. Is prohibited. And now,
A trowel that stretches hair while sandwiching it with two heated flat plates, a strainer that stretches while rolling with two round bars, and a comb are used.

[0004]

However, in the method using the trowel, the hair is damaged and the hair may be broken in some cases when the pressure applied by the heated flat plate is too strong. Attention and skill are required. The method using a strainer is less dangerous than a trowel, but hair is likely to be cut if the sandwiching pressure is too high, and the effect is small if the pressure is too low. The method using a comb requires less labor and skill than the former two, and is safe, but it has a poor hair-stretching action, and thus requires the use of a stronger hair straightening agent. Hair damage may occur from the surface.

By the way, originally, the curly hair straightening is to extend the hair to people having curly hair and straighten it to obtain a cosmetic effect. However, these days, it has come to be used not only for this purpose but also for the purpose of improving the appearance and feel of hair by applying it to people who have slight false hair or straight hair. Therefore, the chances of hair straightening treatment increase, and accordingly, even a person who is not specially trained can easily perform it, and there is little damage to the hair, and a hair straightening that gives a good finished appearance and feel. There is a strong demand for the development of surgery. The present invention seeks to meet those needs by improving combs, which are safe and safe to operate, to provide greater hair-stretching action without the use of strong agents.

[0006]

According to the first and second aspects of the present invention, a comb (1) for straightening hair is formed by sintering a ceramic material capable of irradiating far infrared rays and molding it into a comb shape. And a comb (1) for straightening hair, which is formed by molding a plastic containing approximately 5 to 50% by weight of a ceramic material capable of irradiating far infrared rays into a comb shape.

As the ceramic materials used for these, water is used so that far-infrared rays emitted therefrom can activate water and tissues in the hair as much as possible to promote and improve the penetration and reactivity of the drug. At wavelengths where the electromagnetic wave absorptance is high, that is, peaks appearing in the electromagnetic wave absorption spectrum of water around 3μ and 6μ, and the absorptance is again 11μ.
It is preferable to selectively irradiate infrared rays in the above wavelength range. For example, silica as the main component and alumina 10%
The ceramics and the like contained above meet this preferable condition.

In the case of a plastic hair straightening comb containing a ceramic material, a substantial far-infrared irradiation effect is not expected to be achieved when the amount of the ceramic material added is approximately 5% or less. Molding becomes difficult. Also,
In the case of the plastic comb, the ceramic material may be powdery or fibrous, and the ceramic material may be dispersed almost uniformly in the entire plastic, or fibrous. It may be in the form of a laminated composite of a ceramic material and a plastic.

According to a third aspect of the present invention, each of the above-described hair straightening combs (1) has a plate-shaped electric heater (2) in its main body. In this case, the electric heater may be embedded in the comb body, or may be attached to both sides or one side of the front and back of the comb body.

According to the invention of claim 4, the hair straightening comb (1) of claim 1 or 2 which does not have an electric heater as in the comb of claim 3 is conveniently heated to an appropriate temperature. A method for straightening hair, which is used for straightening hair, and is used for straightening hair after preheating the main body of the comb in a comb heater (3) having an internal temperature of about 40 to 80 ° C. The method of using the comb (1) for straightening hair according to claim 1 or claim 2. The comb heater may be a hollow box-shaped electrothermal heater having a lid or a cover with a slit that allows the main body of the comb to be freely put in and taken out. Is preferred.

[0011]

The comb (1) for straightening hair according to claim 1 or 2
When applying a reducing agent to curly or curly hair and then extending the hair with the comb, if the comb is unheated, it receives heat energy from the human head and so on. In the case where the comb body is heated by an appropriate means, the hair is irradiated with far-infrared rays, which has a strong permeability from the ceramic, which is a composition of the comb, and has a strong permeability, and reaches the deep part of the hair tissue. Therefore, although the surface of the hair is generally made of dense tissue or “hair scalp” and resists the penetration of water and chemicals, the tissue is irradiated by the far infrared rays. The moisture and tissue in the hair are evenly activated to the inside of the hair, the permeation and reaction of the reducing agent are activated and promoted, and the disulfide bond of the hair tissue is uniformly cut to the inside by the reducing agent. When the whole hair loses its resilience It is easy for plastic deformation to occur in the hair, and straightening, that is, straightening operation of curly hair or curly hair by using a safe comb with less risk of hair damage It will be very effective.

[0012] When the curly hair is straightened using a reducing agent as described above, the cut disulfide bond of the hair tissue is recombined with an oxidizing agent to restore the shape retention of the hair. Similarly, in order to efficiently fix the straight hair state of the hair, it is necessary to uniformly oxidize the hair not only on the surface but also on the internal tissue to rebond the disulfide bond. 2 hair straightening combs (1)
When performing the operation of extending the hair coated with the oxidant using, the moisture and the tissue in the hair are uniformly activated to the inside of the tissue by the action of far infrared rays irradiated from the comb,
As a result of the permeation and reaction of the oxidizing agent being activated and promoted, a high degree of shape retention of the straight hair state can be obtained.

According to the third aspect of the invention, the plate-shaped electric heater (2) heats the comb body to an appropriate temperature so that the comb body is not deformed and the hair or scalp is not damaged. From the ceramics, which is a component of the comb body, strong far-infrared rays are emitted based on abundant thermal energy. The shape-retaining effect is enhanced.

According to the invention of claim 4, when using the comb of claim 1 or claim 2 which does not have such an electric heater (2) in the comb body itself, it is used every time when using the comb. It is possible to easily use a comb held at a moderately high temperature, and it is possible to perform an effective hair straightening operation while irradiating economically strong far infrared rays with the comb.
