Method of adding hair and hair-adding device using the same

The present invention relates to a method of adding hair and a hair adding device using the same, in which the added hair is fixed to a thin hair of a human scalp or to a wig of a wig in order to make the number of hair strands on the scalp or the wig relatively large.

One widely used technique is: in the early stage of alopecia, when more hair is left, the hair left on the scalp is utilized to add hair to each hair strand on the scalp of people so as to relatively increase the total amount of hair on the scalp. Yet another widely used technique is: when a new wig is made, a small amount of wig is implanted into the bottom of the wig in advance according to the customer's request to increase the amount of hair properly, or when the portion of the wig implanted into the wig falls off after the wig is used for a long period of time, an additional amount of wig is added to the remaining portion of hair in the wig, thereby relatively increasing the amount of wig on the wig.

For example, japanese laid-open patent publication No. sho61(1986) -97409 discloses a method of fixing a single-strand or multi-strand added hairpiece to a strand of natural hair on the scalp of a person by adhesion. According to this method, a single strand or 2-6 strands of the extension hairpiece cut to a suitable length are aligned at one end and laid along a strand of natural hair, and then the ends of the extension hair are fixed to the roots of the natural hair using an adhesive to branch them. Silicone, polyurethane or epoxy may be used as the adhesive.

However, since the adhesive of silicon or urethane resin is cured for a long time, the workability is poor. On the other hand, the epoxy resin adhesive may cause skin itching, rash, eruption, etc., and is therefore unsuitable from the safety viewpoint. To overcome these problems, a method of thickening hair has also been proposed in which a hot-melt adhesive is used in place of the above adhesive. This method has been disclosed as an invention of the present applicant at 28.6.1991, and its japanese laid-open patent publication No. He: 3(1986) -152205. According to this method, a set of additive hairs is spirally wound around a region near the root of a strand of natural hair, and then a hot-melt adhesive is applied to a region near the ends of the set of strands of hair and the hardened hot-melt adhesive is softened by heating and fixed to the strand of natural hair. Thereafter, it is left at room temperature until the adhesive cools and hardens, so that the hair added is firmly fixed to the natural hair.

Since the time required for the hot-melt adhesive to soften and harden is not long, workability is good. In addition, the hot-melt adhesive hardly reacts with hair and is therefore safe. However, since the strands of hair added are fixed to the natural hair under the condition that the hot-melt adhesive is melted by heat, a certain device such as a heated trowel is used when the strands of hair added are attached to the natural hair, which causes difficulty in handling. In addition, when the trowel heated at high temperature is inadvertently brought into contact with the scalp for a long time, the scalp may be scalded.

In any case, according to the teaching of the above technique, when fixing the supplemental hair to the vicinity of the root of the natural scalp on the scalp of a person, a strand of natural hair is grasped with the fingers of one hand while maintaining this state, a hair implanting needle held with the fingers of the other hand is attached to the substantially central portion of the folded portion of the supplemental hair, and then the needle is carefully operated so that the supplemental hair is wound around the vicinity most likely to be close to the root of the natural hair. The free end of the natural hair is then inserted into the annular folded-over portion and secured tightly. It follows that to fasten several strands of extension hair to a natural strand of hair requires a rather cumbersome task, forming loops or rings of extension hair at the fingers of one hand while holding a natural strand of hair with the fingers of the other hand. Obviously, a considerable working time is required to fix the supplemental hair to, for example, 1000 or more natural hair strands.

From the above viewpoint, a technique is proposed by Japanese patent publication No. Hei7-96722 (10/18/1995). According to this document, several groups of combinations of added hair strands are previously wound around a sleeve at suitable intervals. Then, when the extension hair is fixed to the natural hair of the scalp of a person, a strand of natural hair is inserted into the sleeve, and in this state, the extension hair on the head side is gradually removed from the sleeve, wound around the strand of natural hair, and tightly fixed. However, this technique has the disadvantage that one or more groups of supplemental hair may slip or loosen in place as they are wrapped around the sleeve, and adjacent groups of supplemental hair may become tangled, thus preventing the supplemental hair from being removed from the sleeve smoothly, one by one.

U.S. patent No.5497796 discloses an additive hair holder in which additive hair is aligned and held at one end so that adjacent groups of additive hair do not tangle with each other.

The use of such a holder does allow adjacent groups of hair extensions to be held flat without tangling with each other, but the sleeve must be removed from the base plate during hair extension, which is also quite complicated.

In view of the above, it is an object of the present invention to provide a method of adding hair which enables anyone to perform the hair adding operation conveniently and efficiently in a short time.

Another object of the present invention is to provide a hair adding device in which hundreds or thousands of strands of added hair are prepared in advance so that a hairdresser or stylist can use them instantly, thereby making it possible to perform a hair adding operation efficiently.

According to one aspect of the present invention, there is provided, in general, a method of applying hair to the natural hair of a person's scalp, the method comprising the steps of: wrapping additional hair around a rod at predetermined intervals one by one and loosely tied to the rod, one end of the rod having a flexible annular portion; inserting a natural strand of hair on the person's scalp into the annular portion and withdrawing the supplemental hair wound around the rod and loosely tied thereto from the annular portion unit by unit; pulling the opposite end of the extension hair tightens the exiting extension hair at the fastener, so that the extension hair is secured to the natural strands of hair at the fastener.

The supplemental hair is preferably provided in groups of several strands (e.g., 3 strands), each group being wrapped around the rod at substantially equal intervals and loosely attached to the rod.

The rod is preferably a cylinder and the annular portion is preferably fixedly inserted into one end of the rod.

According to this method of applying hair, in order to fix the hair to growing hair, the growing hair is first inserted into the loop portion of the end of the rod member, and then a group of strands of the applying hair wound around and loosely attached to the rod member is withdrawn through the loop portion, and the growing hair is also withdrawn from the loop portion of the rod member, so that the growing hair is easily penetrated into the fastener of the applying hair, and after the growing hair is penetrated into the fastener of the applying hair, the applying head is issued to the root of the growing hair, and then the opposite end of the applying hair is pulled in the opposite direction, so that the applying hair is easily fastened to the growing hair. Therefore, according to the present invention, since it is not necessary to form a loop and fasten each time the additional hair is applied, the hair application operation is simplified and the work efficiency is improved.

The rod may have a number of beads loosely threaded thereon, and supplemental hair may be wrapped around the rod between the beads and loosely tied to the rod.

According to the characteristic that the beads are loosely threaded on the rod, when the beads behind the hair to be added are pushed by hand to slide in order to withdraw the hair from the rod, the hair in front of the beads is pushed along with the sliding of the specific beads. This allows the additive hair to be easily withdrawn from the wand. In addition, since each set of additive hairs is sandwiched by the beads alternately arranged at predetermined intervals, the additive hairs of the adjacent cells can be prevented from being entangled with each other.

According to another aspect of the present invention there is provided a method of applying filler hair to fasten filler hair to the natural hair of a person's scalp, the method comprising the steps of: wrapping and loosely tying additional hair around an inner rod member, having a flexible annular portion at one end, group by group at predetermined intervals; inserting the inner rod with the supplemental hair into the outer barrel member such that at least the annular portion of the inner rod extends from one end of the outer barrel member; inserting a natural strand of hair on the scalp of the person into the annular portion, and withdrawing additional hair wound around the inner rod member and loosely tied thereto group by group through the annular portion; pulling the opposite end of the extension hair tightens the exiting extension hair at the fastener, such that the extension hair is tied to the natural strand of hair at the fastener.

According to this method of adding hair, since the adding hair is pushed and placed in the outer cylinder member which is not used in the existing hair adding operation, the adding hair does not sag loosely. The hair-up operation can be performed more efficiently. In addition, since the additive hairs are placed in the outer cylindrical member, the additive hairs can be prevented from being tangled with each other.

According to another aspect of the present invention, there is provided a hair-plating device comprising a rod having a flexible loop portion at one end thereof, the rod having hair-plating hair wound thereon, the hair-plating hair being wound around the rod group by group at predetermined intervals and loosely tied thereto.

According to the present invention, since the rod has the ring-shaped portion at one end thereof, in order to attach supplemental hair to growing hair, the growing hair is inserted into the ring-shaped portion, and then the supplemental hair wound around and attached to the rod is withdrawn through the ring-shaped portion group by group, and the growing hair is also withdrawn from the ring-shaped portion. Through such a simple operation, the growing hair can be easily threaded into the fastener to which the hair is added. Therefore, according to the present invention, since it is not necessary to form a loop or a loop on the additional hair and fasten each time when the operation of adding hair is performed, the operation of adding hair is simplified and the working efficiency is improved.

The rod may have a number of beads loosely threaded thereon, and supplemental hair may be wrapped around the rod between the beads and loosely tied to the rod.

According to the characteristic that the beads are loosely threaded on the rod, when the beads behind the hair to be added are pushed by hand to slide the beads in order to withdraw the hair from the rod, the hair in front of the beads is pushed as the particular beads slide. This allows the additive hair to be easily withdrawn from the wand. In addition, since each group of supplemental hairs is sandwiched by the beads alternately arranged at predetermined intervals, the supplemental hairs of the adjacent groups can be prevented from being tangled with each other.

The rod may be tapered, with a decreasing diameter at one end having the annular portion and a gradually increasing diameter towards the other end. Due to the tapered shape (gradually decreasing in diameter toward the distal end side having the annular portion) of the rod, the supplemental hair located near the distal end side is easily withdrawn from the rod. To prevent the supplemental hair wound around the rod and loosely tied thereto from becoming entangled with each other, the tapered rod may have notches formed at predetermined intervals along its circumferential surface, the notches being so small that it just receives a group of supplemental hair, each group of supplemental hair being placed in the notch, so that the supplemental hair does not slip accidentally. This feature also prevents adjacent supplemental hair strands from becoming entangled with one another.

In addition to the tapered rod, the rod may also be of a multi-stage expandable type. Due to this characteristic, when the fixing operation in which the filling hair is wound around the first rod positioned at the distal end side and loosely tied thereto is completed, the sliding distance of the filling hair can be shortened by inserting the first rod into the second rod, and thus the filling hair operation can be completed more efficiently.

According to another aspect of the present invention, there is provided a hair adding device comprising an inner rod having a flexible annular portion at one end thereof, and additive hair wound around the inner rod group by group at predetermined intervals and loosely tied thereto, and an outer cylinder for accommodating the inner rod around which the additive hair is wound, at least the annular portion of the inner rod being caused to protrude from one end of the outer cylinder.

According to this structure, since the filling hair is pushed into the outer cylinder member and placed in the outer cylinder member together with the inner rod member, the filling hair does not hang down loosely, which is not adopted in the prior art operation of filling hair. Thus, the hair adding operation can be performed more efficiently. In addition, since the additive hairs are placed in the outer cylindrical member, the additive hairs are not tangled with each other.

The inner rod member and outer barrel member may be made from a small, large hard plastic cylinder of approximately the same length.

The rod or inner rod to which the hair is attached may have cuts or grooves along its length for inserting hook type hair grafts therein. Due to the cut or groove, the hair can easily be caught by the hair setting needle and pulled towards the loop side. When the bar or inner bar is a cylindrical body, the bar may be C-shaped in cross-section for ease of machining the above-mentioned cuts.

The supplemental hair used in each of the above inventions may be in the form of a plurality of strands of supplemental hair grouped together into a set of supplemental hair so that they are wrapped around and loosely tied to the inner rod member in generally equally spaced groups.

A large hair extension device can be formed by fixedly placing 50 groups of hair extension devices in parallel on a tray, where each group of devices has 50 strands of hair extension groups. According to this arrangement, since 2500 additional hair sets are fixed to the large-sized additional hair device, they are maintained in the fastened state, and thus the hair adding operation can be performed more efficiently.

The present invention will be understood more fully from the detailed description given below and from the accompanying drawings of preferred embodiments of the invention, which, however, should not be taken to limit the invention, but are for explanation and understanding only.

A method of applying hair and a hair application device used therefor will be described below with reference to fig. 1 to 8.

Referring initially to fig. 1, one embodiment of the hair-plating device of the present invention is shown. The hair-adding device 10 mainly comprises a bar 11; hair 12 wound around the outer peripheral surface of the rod 11 at a predetermined interval and loosely tied thereto; the flexible filament 13 forms a loop portion 13a which is fixed to the distal end side of the rod 11 in such a manner as to project from the distal end side.

The rod 11 is a solid or hollow body of plastic, wood or metal material, and the rod 11 is preferably made of a material that is sufficiently stiff or strong so that it will not break or bend excessively due to the weight of the supplemental hair 12, particularly when a large quantity of supplemental hair is wound around the rod 11 and tied thereto. The loop portion 13a at the distal end of the rod member 11 is formed by bending a filament 13 made of a flexible material, preferably plastic. The free end of the annular portion 13a is inserted into the end of the rod 11 and fixed.

The added hair 12 is selected from natural human hair or artificial hair that is consistent in color, thickness and length with growing hair on the scalp of a person in need of multiple hairs. Generally, the breaking load of the added hair 12 is 100 to 250g, preferably 200 to 250 g. The diameter of the additive hair is preferably 60 to 80 μm, and the group of additive hair 12 is composed of single additive hair 12. In this case, in order to attach the filling hair 12 to the rod 11, a single filling hair constituting a set of filling hairs is folded into two, and in this state, the folded-back portion is wound around the rod 11 and then folded into two to form a loop portion. The opposite end of the supplemental hair 12 is then inserted into the loop portion. By doing so, the additive hair 12 is attached to the rod 11. Preferably, the set of supplemental hair 12 is comprised of a plurality of supplemental hair strands (e.g., 3 strands). In this case, a water-insoluble glue is applied uniformly to the surface of the additive hair 12, so that it forms a thin layer. The hair 12 with the thin layer of glue applied thereon is then set aside for 1-3 minutes to dry.

In order to perform a hair adding operation using the upper-speed hair-setting device 10, a natural stream of hair from the scalp of a person requiring more hair is first threaded into the annular portion 13a of the rod 11, and then the forward hair-setting portion 12 is moved to a position and is withdrawn from the rod 11 through the annular portion 13 a. While the natural hair is also drawn down through the annular portion 13 a. As a result, natural hair can be passed through the fastening portion of the extension hair 12. In this case, when the free ends of the filling hair 12 are pulled in the opposite direction, the filling hair 12 is tightly tied to the natural hair. The hair adding operation is described in more detail below with reference to fig. 3 and 8.

In the first embodiment, the supplemental hair can be easily fixed to the natural hair on the scalp of a person by using the loop portion 13a formed on the distal end of the rod 11. On the contrary, the supplemental hair 12 wound around the rod 11 and loosely tied thereto may slip, closely contact or tangle with the adjacent supplemental hair 12. For this reason, a hair-setting device, which will be described below, can be used, which allows a predetermined interval not to be changed, and thus adjacent hair sets to be less likely to be tangled with each other.

The hair adding apparatus 20 of the second embodiment in fig. 2 includes: a rod member 21; supplemental hair 22 wound and loosely tied on the outer peripheral surface of the rod 21 at predetermined intervals; a loop portion 23a formed of the filament 23, which is flexible and located at the tip side of the rod 21 and extends beyond the tip side; and a plurality of beads 24 loosely fitted on the stick 21. The additive hairs 22 and the beads 24 are alternately arranged on the rod 21.

When the hair adding operation is performed using the above-described hair adding device 20, as shown in fig. 3(a) to 3(E), first, as shown in fig. 3(a), a natural hair H on the scalp of a person who needs more hair is threaded into the loop portion 23a at the end of the rod 21, and then the front beads 24a are slid to press the additional hair 22a located in front thereof. Finally the bead 24a exits through the loop portion 23 a. The sliding of the beads 24a causes the beads 24a to push the supplemental hair 22a on the side of the looped portion 23a, thus causing the supplemental hair 22a to be withdrawn from the looped portion 23a of the filament 23 together with the beads 24 a. When the loop portion 24a of the filament 23 is withdrawn from the natural hair H as a needle, the natural hair H is inserted into the fastener of the supplemental hair 22a as shown in fig. 3 (C). Finally, when the opposite ends of the supplemental hair 22a are pulled in opposite directions as shown in fig. 3(D), the supplemental hair 22a is tightly tied to the natural hair H as shown in fig. 3 (E). To perform the hair adding operation, the process is repeated as many times as the number of groups to which the hair strands are added. Reference numeral S denotes the scalp surface of a person who needs more hair.

According to the hair setting device of the second embodiment, since the set hairs 22 are positioned at predetermined intervals by the placement of the beads 24, the set hairs 22 do not move into close contact with and get tangled with the adjacent set hairs 22.

However, there still remains a problem in that it is time-consuming and troublesome to slide the beads 24 along the rod 21 which penetrates the beads and extends through the beads 24, and it is necessary to restore the original shape after the beads are removed from the rod 21 in the hair adding operation.

From the above point of view, the third embodiment of the hair-adding device shown in fig. 4 and 5 will be described as the best embodiment of the present invention.

Fig. 4 is an exploded perspective view of a third embodiment of the hair adding device 30 of the present invention.

The hair-adding device 30 generally comprises: an inner rod member 31 made of plastic; hair 32 is wound and loosely tied on the outer peripheral surface of the inner rod 31 at predetermined intervals; a flexible filament 33 having opposite ends 33b fixed to the inner rod member 31 and an intermediate ring portion 33a extending from one end of the inner rod member 31; and an outer tubular member 34 for receiving the inner tubular member 31, the received inner tubular member 31 having additive hair 32 wound therearound and loosely tied thereto, at least a looped portion 33a of the filament 33 projecting from one end of the outer tubular member 34.

As shown in fig. 5, the inner rod member 31 wound and loosely tied with the filling hair 32 is first inserted completely into the outer barrel member 34 from the annular portion 33a side and is seated therein. Thus causing the annular portion 33a on the end of the inner rod member 31 to project from the other end of the outer tubular member 34.

In this embodiment, although the inner rod member 31 is formed of a cylindrical body, the present invention is not limited to the cylindrical body, and other configurations may be employed such that only the opposite ends of the filaments 33 of the ring portion 33a are fixed to one end of the rod-shaped body. Likewise, the outer surface profile of the inner rod member 31 should not be limited to the planar shape shown in FIG. 3. In the alternative, the outer surface of the inner rod member 31 may be slightly uneven to prevent the supplemental hair wound around and loosely tied to the inner rod member 31 from becoming tangled with each other as the supplemental hair slips.

A method of winding and loosely tying a set of strands of supplemental hair 32 around the outer circumferential surface of the inner rod 31 using the hair setting device 30 of the third embodiment is described below with reference to fig. 6.

First, as shown in fig. 6(a), the filling hair is folded into two strands and held with one hand, and then, as shown in fig. 6(B), the inner rod member 31 is inserted into the U-shaped portion 32c formed by folding the filling hair 32 into two strands. Then, the inner rod 31 is rotated in the direction indicated by the arrow A, so that the half 32b of the additional hair 32 is hooked on or straddles the one end 31b of the inner rod 31. Thus, the hair 32 is added in a figure-8 shape as shown in fig. 6 (C).

Thereafter, the inner rod 31 is rotated clockwise as shown by the arrow B to form a ring 32c as shown in fig. 6 (D). Next, as shown in fig. 6(E), the one end 31b side of the inner rod member 31 is turned downward from the intersection of the two halves 32a, 32b as indicated by an arrow C. Then, as shown in fig. 6(F), the one end 31b of the inner rod member 31 is twisted counterclockwise as shown by the arrow D. As a result, as shown in FIG. 6(F), a U-shaped portion 32e is formed on the filling hair 32. Then, the one end 31b of the inner rod member 31 is turned downward as shown by an arrow E in fig. 6(F) and inserted into the U-shaped portion 32E, forming the same as shown in fig. 6 (G). Next, as shown in fig. 6(H), the half 32b of the filling hair 32 is pulled out from the space 32 f. Finally, as shown in fig. 6(I), the opposite ends 32a, 32b of the filler hair 32 are pulled slightly to form a release button. Since the additional hair 32 is wound around the inner rod member 31 four times, the fastener is not loosened.

The above-mentioned process is repeated as many times as the number of groups of the additional hair strands 32 so that the additional hair strands 32 are wound around the inner rod member 31 at predetermined intervals and loosely tied thereto. By doing so, the hair-setting device 30 is completed.

It should be noted that the method of wrapping and loosely tying the filling hair 32 around the inner rod member 31 will not be limited to the above-described method. Other similar methods may be used as long as the supplemental hair 32 wound around the inner rod member 31 and loosely tied thereto can be slid toward the annular portions 33a side of the filaments 33 on the outer peripheral surface of the inner rod member 31, and when the supplemental hair 32 is tightly tied to the natural hair H, it does not loosen.

The additional hair 32 is wound around the inner rod member 31 at predetermined intervals and loosely tied thereto in the above-described manner, and the inner rod member thus completed is inserted into the outer cylinder member 34 from the end having the loop member 33a as indicated by the dotted line with an arrow in fig. 4. The result is that the filling hair 32 is located between the outer barrel part 34 and the inner rod part 31. This prevents the filler hair 32 from hanging loosely down from the hair setting device 30, allowing a person performing the hair setting operation, such as a hairdresser or stylist, to concentrate on the hair setting operation without interference from the filler hair 32.

If a plurality of hair adding devices 30 according to the present invention are prepared in advance in the above-described manner, the hair adding operation can be performed orderly. If several hair-adding devices 30 are arranged parallel, fixedly on the plate 40, as shown in fig. 7, the amount of added hair used is clear at a glance and therefore more convenient. For example, by arranging 50 rows of the adding devices 30 (each consisting of 50 adding hair sets wound around and loosely tied to one adding device 30) on the support plate 40, the adding operation can be conveniently performed using a total of 2500 adding hair sets. This is of great benefit to both the operator and those who require more hair.

Next, a method of adding hair of the present invention using the hair adding device 30 of the third embodiment will be described with reference to fig. 8.

As shown in FIG. 8(A), a single strand of hair H is inserted into the loop portion 33a, the inner rod member 31 is gently pushed out as indicated by the arrow V, and then a group of additional hair strands 32 is gently moved rightward by pinching with the fingers of one hand or by needle-lifting, as shown in FIG. 8(B), so as to be withdrawn from the inner rod member 31, and the knotted loops 32J of the additional hair strands 32 are fitted over the outer periphery of the loop portion 33 a. Then, the inner rod member 31 and the outer tubular member 34 are moved in the direction of the arrow W while pinching the knotted ring 32j of the additional hair 32 with fingers, and the natural hair H is folded into two parts while removing the knotted ring 32j of the additional hair as shown in FIG. 8 (C). At this time, the free end side of the additive hair 32 is withdrawn or pulled out from the space between the outer tubular member 34 and the inner rod member 31. When the inner rod 31 and the outer barrel 34 are further moved leftward as indicated by the arrow X in FIG. 8(D), the set of supplemental hair 32 is separated from the supplemental hair device 30 and the natural hair H is loosely fitted in the knotted ring 32 j. The knotted loop 32j is then pressed down as indicated by arrow Y towards the root of the natural hair H until it comes into contact with the scalp S. Then, as shown in fig. 8(E), the opposite ends 32a, 32b of the additive hair 32 are pulled in opposite directions in the direction of the arrow E, and the knot is fastened to tie the additive hair 32 tightly to the natural hair H. In so doing, as shown in fig. 8(F), a plurality of additional hair strands 32 are thickly grown from a strand of natural hair H. To this end, one cycle of the hair addition operation is completed. Then, as shown in fig. 8(G), the loop portion 33a is moved so that the next natural hair to be treated is inserted into the loop portion 33a, the inner rod member 31 is slightly withdrawn from the outer cylindrical member 34 by a distance L to expose the next additional hair strand, and the cycle is repeated.

It can be seen that the size of the ring portion 33a is constant in any cycle as long as the desired natural hair H can be inserted into the ring portion 33a and densified. Thus enabling the hair-filling operation to be performed better. In addition, in one cycle of the operation of adding hair, all the groups of adding hair 32 are placed in the space between the outer barrel member 34 and the inner rod member 31 before the state shown in fig. 8 (D). Therefore, since the attachment hair 32 does not loosely hang down around the natural hair H, the operation of attaching hair is made easier. In this way, the high level of worker attention and effort required for the hair adding operation can be significantly reduced.

The rod or inner rod used in the hair-adding device of the present invention, around which the hair additive is wound and loosely tied, is not limited to the examples shown in the drawings, but may be variously modified. For example, as shown in FIG. 9, a tapered rod member 41 having a diameter increasing at its root end side and gradually decreasing toward its tip end side may be used. Due to the characteristic of the reduced diameter of the tip, the supplemental hair located near the root end side can be easily withdrawn when necessary. In order to prevent additive hair wound around and loosely tied to the rod 41 from slipping, as shown in fig. 10, if a plurality of notches 41a (or protrusions) are arranged at predetermined intervals on the circumferential surface of the rod 41, each of which is small enough to receive a strand of additive hair, adjacent additive hair is prevented from being tangled with each other.

In addition to the tapered rod member, the rod member may be of a multi-stage easy-expansion type as shown in fig. 11, in which case the first rod 51a is inserted into the second rod 51b after the hair fixing operation is completed, i.e., immediately after additional hair is wound around and loosely tied to the first rod 51a on the distal end side as shown by the annular portion 52. In this way, the sliding distance required to add hair is reduced, and the hair adding operation can be performed more efficiently.

Fig. 12 shows another example of the rod 61 (or inner rod). The rod 61 is a cylindrical body having a slit 61a extending over the entire length thereof. The bar 61 is thus C-shaped in cross section with the cut 61a, so that when the filling hair 62 is moved toward the loop part 63a side using a hook-type hair setting needle (not shown), the filling hair 62 is easily caught by the hook part of the hair setting needle, and the needle with the hair 62 can easily slide toward the loop part 63a side.

When the bar 61 (or inner bar) is solid, the depth of the lengthwise cut (notch) in the surface of the bar 61 is just enough to insert the crochet needle.

Of course, the invention is also applicable to the case where the thin hair is relatively dense. In addition, the invention is also suitable for the situation that the hairpiece part on the hairsleeve falls off and needs to be repaired by adding hair. In this case, the phrase "natural hair on human scalp" is preferably "wig on wig". It is therefore to be understood that the above situations are included within the scope of the present invention.
