Detailed description of the invention

Hereinafter, embodiments and examples for carrying out the present disclosure will be described with reference to the drawings. The wig base and wig described below are for embodying the technical idea of the present disclosure, and the present disclosure is not limited to the following unless otherwise specified. The size and positional relationship of the members shown in each drawing may be exaggerated for the sake of clarity.

(Jig for hair extension according to one embodiment of the present disclosure)
First, the outline of the structure of the extension jig according to one embodiment of the present disclosure will be described with reference to FIG. FIG. 1 is a perspective view schematically showing the structure of a hair extension jig according to one embodiment of the present disclosure.

The hair extension jig 2 according to the present embodiment includes a hollow cylindrical member 4, a plurality of notches 10 for artificial hair provided in the outer shell 6 of the hollow cylindrical member 4, and an outer shell 6 of the hollow cylindrical member 4. It is provided with one notch 20 for own hair provided.
In the hair extension jig 2 shown in FIG. 1, ten artificial hair notches 10 are arranged side by side in the longitudinal direction of the hollow cylindrical member 4. However, the number of notches 10 for artificial hair is not limited to 10, and any number of 2 or more can be adopted. The hair cut portion 20 is provided on one end 4A side of the hollow cylindrical member 4.

As will be described later, the artificial hair to be the hair extension is inserted into the notch of the artificial hair notch 10 of the hair extension jig 2 and attached. Using the artificial hair attached to the artificial hair notch 10, a loop is formed so as to surround the hollow cylindrical member 4 to form a knot. The artificial hair formed in this way is called a hair extension. After that, by inserting the user's own hair into the notch of the own hair notch portion 20, the hair extension jig 2 to which a plurality of hair extensions are attached can be attached to the user's own hair.

The hollow cylindrical member 4 is preferably formed of an elastic resin material. The outer diameter of the hollow cylindrical member 4 can be exemplified from 5 mm to 20 mm. If the length of the hollow cylindrical member 4 is short, the number of notches 10 for artificial hair to be installed is small, and if it is long, the weight is increased and it is easy to come off when attached to the own hair. Therefore, it is preferable to determine the number of cuts for artificial hair 10 to be installed according to the application, and to determine the optimum length according to the number. As the length of the hollow cylindrical member 4, 30 mm to 100 mm can be exemplified. As the thickness of the outer shell 6 of the hollow cylindrical member 4, 0.2 mm to 0.6 mm can be exemplified. For example, a commercially available resin straw can be used as the hollow cylindrical member 4.

<Notch for artificial hair>
Next, the notch portion 10 for artificial hair will be described in detail with reference to FIG. FIG. 2 is an enlarged perspective view showing a cut portion for artificial hair of the hair extension jig shown in FIG. 1.
The fake hair notch 10 has a fake hair cantilever 12 formed of a part of a cantilever-shaped outer shell 6 connected to the outer shell 6 at the base end portion 12A by a notch provided in the outer shell 6. .. The artificial hair is sandwiched and held between the artificial hair cantilever portion 12 and the outer shell 6. Since the hollow cylindrical member 4 has elasticity, the cantilever beam formed by the cantilever portion 12 for artificial hair receives a force in the closing direction toward the outer shell 6 side, and can securely sandwich and hold the artificial hair.

In the present embodiment, the artificial hair cantilever portion 12 has a substantially triangular shape having a first side 12A composed of a base end portion, a second side 12B defined by a notch, and a third side 12C. By having such a shape, the cantilever portion 12 for artificial hair can be easily formed by linearly cutting out in a V shape.
However, the cantilever portion 12 for artificial hair is not limited to the case where it has a substantially triangular shape, and may have a curved outer shape or an arbitrary polygonal shape of a quadrangle or more. .. Any shape can be adopted depending on the application.

In the present embodiment, a plurality of notches 12 for artificial hair are arranged side by side in the longitudinal direction of the hollow cylindrical member 4. By arranging the plurality of artificial hair notches 12 side by side in the longitudinal direction of the hollow cylindrical member 4, many artificial hairs can be efficiently arranged without deteriorating workability.

<Notch for own hair>
Next, the cut portion 20 for own hair will be described in detail with reference to FIGS. 3 and 4. FIG. 3 is an enlarged perspective view showing a cut portion for own hair of the hair extension jig shown in FIG. 1. FIG. 4 is a cross-sectional view showing a BB cross section of FIG.
The self-hair cut portion 20 has a self-hair cantilever portion 22 formed of a part of a cantilever-shaped outer shell 6 connected to the outer shell 6 at the base end portion 22A by a notch provided in the outer shell 6. .. The own hair is sandwiched and held between the cantilever portion 22 for the own hair and the outer shell 6. Since the hollow cylindrical member 4 has elasticity, the cantilever beam by the cantilever portion 22 for own hair receives a force in the closing direction toward the outer shell 6 side, and can surely sandwich and hold the own hair.

More specifically, an elastic member 24 having an outer shape larger than the outer shape of the self-hair cantilever portion 22 is attached to the inner surface side of the self-hair cantilever portion 22. The elastic member 24 is preferably made of a resin material. For example, the elastic member 24 can be fixed to the inner surface of the cantilever portion 22 for own hair by using an adhesive.
The elastic member 24 may cover the entire inner surface of the cantilever portion 22 for own hair, or may cover only the outer peripheral side of the inner surface of the cantilever portion 22 for own hair. When the elastic member 24 covers the entire inner surface of the self-hair cantilever portion 22, the self-hair is sandwiched and held between the self-hair cantilever portion 22 and the outer shell 6 via the elastic member 24. Will be done.

As shown in the cross-sectional view of FIG. 4, since the elastic member 24 having an outer shape larger than the outer shape is attached to the inner surface side of the own hair cantilever portion 22, the own hair cantilever portion 22 (elastic member 24). ) And the outer shell 6 with their own hair sandwiched between them, at least a part of the elastic member 24 is in contact with the inner surface 6C of the opening of the outer shell 6 or the inner surface 6B of the outer shell 6 generated by the notch. ..
In the region where the hair is sandwiched, the elastic member 24 is located above the outer surface 6A of the outer shell 6, but the cantilever portion 22 for the hair and the elastic member 24 are elastically deformable, so that the operator can perform the hair piece. By pressing the holding portion 22 from above, the elastic member 24 opens the outer shell 6 in at least a part of the area of the holding portion 22 including the tip end side of the own hair cantilever portion 22. It comes into contact with the inner surface 6C or the inner surface 6B of the outer shell 6.

As a result, the hair can be reliably held between the cantilever portion 22 (elastic member 24) for the hair and the outer shell 6. As a result, even if a large number of artificial hairs are attached to the hair extension jig 2 and have a relatively large weight, or even if a force is applied to the hair extension jig 2 during work, the hair It is possible to prevent the extension jig 2 from coming off from the user's own hair.

In the present embodiment, similarly to the above-mentioned cantilever portion 12 for artificial hair, the cantilever portion 22 for own hair has a first side composed of a base end portion 22A, a second side 22B defined by a notch, and a third side. It has a substantially triangular shape with 22C. By having such a shape, the cantilever portion 22 for own hair can be easily formed by linearly cutting out in a V shape.
However, the cantilever portion 22 for own hair is not limited to the case where it has a substantially triangular shape, and may have a curved outer shape or an arbitrary polygonal shape of a quadrangle or more. Any shape can be adopted depending on the application.

<Arrangement of cuts for artificial hair and cuts for own hair>
Next, the arrangement of the artificial hair cut portion 10 and the own hair cut portion 20 will be described with reference to FIG. FIG. 5 is a side view showing the arrow AA of FIG.
As is clear from FIG. 5, the cut portion 10 for artificial hair and the cut portion 20 for own hair are arranged at an angle of approximately 90 degrees in the side view of the hollow cylindrical member 4 when viewed from the longitudinal direction. In this way, by arranging the artificial hair notch 10 and the hair notch 20 at an angle of approximately 90 degrees, the hair attached to the hair notch 20 in the extension mounting work can be combined with the hair. It is possible to prevent the artificial hair attached to the artificial hair notch 10 from interfering with the artificial hair. As a result, the hair extension made of artificial hair can be efficiently attached to the own hair.

Since the cut portion 10 for artificial hair and the cut portion 20 for own hair are arranged at an angle of approximately 90 degrees, the cut portion 10 for artificial hair and the cut portion 20 for own hair are provided in the longitudinal direction of the hollow cylindrical member 4. Even if they are arranged close to each other, it is possible to prevent the self-hair attached by the self-hair notch 20 and the artificial hair attached to the artificial hair notch 10 from interfering with each other during the work.
Therefore, in the present embodiment, the hair cut portion 20 and the artificial hair cut portion 10 are arranged at positions where they overlap each other in the direction orthogonal to the longitudinal direction of the hollow cylindrical member 4. With such an arrangement, a ring formed of artificial hair can be efficiently performed when passing through the cut portion 20 for own hair, and further contributes to miniaturization of the hair extension jig 2.

As is clear from FIG. 1, in the present embodiment, the cut directions of the artificial hair cut portion 10 and the own hair cut portion 20 are oriented in the same direction. Therefore, the ring formed of the artificial hair attached to the artificial hair notch 10 is pulled out from the first side (base end) 12A side to the second side 12B and the third side 12C side, and the artificial hair notch is cut. When removed from the portion 10 and moved in the same direction in the longitudinal direction of the hollow cylindrical member 4, when passing through the hair notch portion 20, the first side (base end portion) 22A to the second side 22B and the third side Since it moves to the 22C side, the ring formed of the artificial hair and the cut portion 20 for own hair can move smoothly without interfering with each other.

(How to attach a hair extension using a hair extension jig)
Next, a method of attaching the hair extension using the hair extension jig 2 according to the present embodiment will be described with reference to FIGS. 6 to 12. 6 to 12 are views showing a method of attaching a hair extension using a hair extension jig, and FIG. 6 is a view showing a plurality of artificial hairs attached to the hair extension jig. FIG. 7 is a diagram showing a hair extension jig to which a plurality of artificial hairs are attached attached to the user's own hair, and FIG. 8 is a hollow cylinder having a ring formed by the first region. It is a figure which shows the place where it moves in the axial direction of a member and passes through the notch part for own hair, and FIG. 9 shows that the ring by the 1st region is moved in the axial direction of a hollow cylindrical member, and one of the hollow cylindrical members It is a figure which shows the place which passed through the end part, FIG. 10 is a figure which shows the place where the user's own hair was inserted into the ring by the 1st region, and FIG. It is a figure which shows the place which moved the ring by a region to a desired position in the longitudinal direction of the own hair, and FIG. It is a figure which shows the place to fix to own hair.

First, a hair extension jig 2 provided with a plurality of notches 10 for artificial hair and one notch 20 for own hair is prepared in the outer shell 6 of the hollow cylindrical member 4 (step 1). Next, the artificial hair G is inserted into the cuts of at least a part of the artificial hair cut portions 10 among the plurality of artificial hair cut portions 10. FIG. 6 shows, as an example, a case where the artificial hair G is inserted into all of the 10 artificial hair notches 10 provided in the outer shell 6 (see the alternate long and short dash line). Then, the outer shell 6 of the hollow cylindrical member 4 is surrounded by the artificial hair G, and a ring R surrounding the outer shell 6 is formed. The portion forming the ring R is referred to as a first region G1, and a knot is formed by using the second region G2 and the third region G3 extending on both sides in the longitudinal direction of the first region G1 (step 2). .. As a result, a hair extension G formed of artificial hair is obtained.

In the method of attaching the hair extension using the hair extension jig 2 according to the present embodiment, since the artificial hair G is attached to the artificial hair notch 10, it is not necessary to hold the artificial hair G by hand. Therefore, since the worker can tie a knot using both hands, the workability is improved and the knot can be formed quickly and easily.
As a method of forming a knot, any known knot method can be applied, and the knot method according to one embodiment of the present disclosure, which will be described later, can also be applied.

Next, as shown in FIG. 7, a hair extension jig to which a plurality of hair extensions G are attached by inserting the user's own hair J into the notch of the own hair notch 20 of the hollow cylindrical member 4. 2 can be attached to the user's own hair (step 3). Then, for the hair extension G closest to the own hair J among the plurality of hair extensions G, the ring R formed by the first region G1 surrounding the hollow cylindrical member 4 is moved in the axial direction of the hollow cylindrical member 4 to cause the own hair. The ring R by the first region G1 surrounding the hollow cylindrical member 4 is passed through the notch 20 (see FIG. 8) and one end 4a of the hollow cylindrical member 4 (see FIG. 9). The hair J is inserted into the hair (see FIG. 10) (step 4).

Next, as shown in FIG. 11, the ring R surrounding the hair J is moved to a desired position in the longitudinal direction of the hair J (step 5). Then, by pulling the second region J2 and the third region J3 extending from the knot M toward the tip side toward the tip side, the ring R surrounding the hair is narrowed and the knot is narrowed down, and the hair extension G is pulled into the hair extension G. Can be fixed to (step 6).
As described above, since the elastic member 24 having an outer shape larger than the outer shape is attached to the inner surface side of the hair cantilever portion 22 of the hair extension cut portion 20, the hair extension jig 2 can be used by the user. It can be securely attached to your own hair. As a result, the operator can perform the operations from step 4 to step 6 using both hands, so that the hair extension G can be easily and efficiently attached to the user's own hair J.

Then, steps 4 to 6 are repeated until all the hair extensions G are fixed to the own hair J (step 7). Then, the hair extension jig 2 is removed from the hair by pulling out the hair J from the notch in the hair notch 20 of the hollow cylindrical member 4 (step 8). In this way, by using the hair extension jig 2, the hair extension made of artificial hair G can be easily and efficiently attached to the user's own hair J.

In particular, in the cut portion 10 for artificial hair and the cut portion 20 for own hair, the hollow cylindrical member 4 is cut from one end 4A side to the other end 4B side, and the outer shell 6 generated by the cut. The opening is arranged on one end 4A side of the base ends 12A and 22A.
As a result, the ring R formed by the artificial hair held by the artificial hair notch 10 can be easily removed from the artificial hair notch 10 by moving it to one end 4A side. Further, when the ring R is moved to one end 4A side and passed through the hair notch 20, it moves from the base end 22A side of the hair notch 20 to the opening side, so that it is for hair. The wheel R can be moved smoothly without interfering with the notch 20.

As described above, the hair extension jig 2 to which a plurality of hair extensions G are attached by the artificial hair cut portion 10 can be attached to the user's own hair by using the own hair cut portion 20. Therefore, the operator can use both hands to form a knot of the hair extension G and to attach the hair extension to the user's own hair. Since the hair J is simply inserted into the notch of the hair notch 20, it can be attached to the hair without damaging the hair, and the hair extension can be easily and efficiently attached to the user's hair. Can be done. In particular, since the hair extension is attached to the hair using the notch 20 for the hair to which the elastic member 24 having an outer shape larger than the outer shape of the cantilever for the hair 22 is attached, the hair extension is surely performed without damaging the hair. The jig can be held on the user's own hair.

Regarding the first region forming the ring R surrounding the outer shell 6 of the hollow cylindrical member 4 or the hair J, and the second region G2 and the third region G3 extending on both sides in the longitudinal direction of the first region G1. The absolute position in the artificial hair changes depending on the size of the ring R. That is, when the ring R is narrowed, the portion of the artificial hair that has been the first region G1 may become a part of the second region G2 or the third region G3. On the contrary, when the ring R is expanded, the portion of the artificial hair that has been the second region G2 or the third region G3 may become a part of the first region G1. In any case, the region forming the outer shell 6 of the hollow cylindrical member 4 and the ring R surrounding the hair J is referred to as the first region, and the region extending on both sides in the longitudinal direction of the first region G1 is the first region. It is referred to as a second region G2 and a third region G3.

(How to attach the hair extension according to one embodiment of the present disclosure)
Next, the method of attaching the hair extension according to one embodiment of the present disclosure will be described with reference to FIGS. 13 to 17. In particular, the method of forming the knot M will be described in detail. 13 to 17 are all views (photographs) using a model showing a method of forming a knot, and FIG. 13 shows an outer shell of a hollow cylindrical member surrounded by artificial hair and the outer shell is surrounded. FIG. 14 is a diagram showing a first region forming a ring, a second region extending on both sides in the longitudinal direction of the first region, and a third region, and FIG. 14 shows the second region as the outer circumference of the third region. FIG. 15 is a diagram showing a knot in which a third region is passed through a ring of single knots formed in a second region by tying a single knot so as to surround the first region. It is a figure which shows the place where the user's own hair is inserted into the ring by passing the ring by the region through one end of the hollow cylindrical member, and FIG. 16 shows the ring by the first region by the own hair. FIG. 17 is a diagram showing a roller in which the ring surrounding the hair is narrowed and brought into close contact by moving the third region to a desired position in the longitudinal direction and pulling the third region toward the tip side with respect to the knot. The figure shows that the knot is narrowed down by pulling the region 2 toward the tip side with respect to the knot, the state of the ring surrounding the hair that is in close contact with the hair is maintained, and the artificial hair is fixed to the hair. is there.

As shown in FIG. 13, a hair extension jig 2'provided with a plurality of notches 10 for artificial hair and one notch 20 for own hair in the outer shell 6 of the hollow cylindrical member 4 is prepared (step 1). , The artificial hair G is inserted into the notch of at least a part of the artificial hair notch 10 among the plurality of artificial hair notch 10.
As the hair extension jig 2', it is preferable to use a hair extension jig in which the elastic member 24 is attached to the cantilever portion 22 for the own hair of the notch portion 20 for the own hair as described above, but this is limited to this. It is not something that can be done. It is also possible to use a hair extension jig that does not have an elastic member and has only a cantilever portion 22 for own hair, similarly to the notch portion 10 for artificial hair.

Then, as shown in FIG. 14, the outer shell 6 of the hollow cylindrical member 4 is surrounded by the artificial hair G, and the second region G1 extending on both sides in the longitudinal direction of the first region G1 forming the ring R surrounding the outer shell 6. Of the region G2 and the third region G3, the second region G2 surrounds the outer circumference of the third region G3 (see arrow S), a single knot is made (see arrow T), and the second region G2 A third region G3 is passed through the loop of the formed single knot (see arrow U) to form a knot M (step 2). As a result, a hair extension G formed of artificial hair is obtained.
Then, the user's own hair J is inserted into the notch of the self-hair cutting portion 20 of the hollow cylindrical member 4, and the hair extension jig 2'attached with the plurality of hair extensions G is inserted into the user's own hair J. Install (step 3).

Next, for the hair extension G closest to the own hair J among the plurality of hair extensions G, the ring R formed by the first region G1 surrounding the hollow cylindrical member 4 is moved in the axial direction of the hollow cylindrical member 4 to cause the own hair. Pass through one end 4A of the notch 20 and the hollow cylindrical member 4. As a result, as shown in FIG. 15, the hair J can be inserted into the ring R formed by the first region G1 surrounding the hollow cylindrical member 4 (step 4). Then, the ring R surrounding the hair J is moved to a desired position in the longitudinal direction of the hair J (step 5).

Then, by pulling the third region G3 extending from the knot M toward the tip side (that is, passing through the loop of the single knot) toward the tip side with respect to the knot M (see arrow V in FIG. 15), FIG. As shown in the above, the ring R surrounding the hair J can be narrowed so that the ring R can be brought into close contact with the hair J. Further, by pulling the second region G2 extending from the knot M toward the tip side toward the tip side with respect to the knot M (see the arrow W in FIG. 16), as shown in FIG. 17, the knot M is narrowed down and self-reliant. The hair extension G formed of the artificial hair can be fixed to the hair J by maintaining the state of the ring R surrounding the hair J in close contact with the hair J (step 6).

When pulling the second region G2 or the third region G3 toward the tip side, the knot M is connected to the knot M by pulling it in an angled direction from the extending direction of the hair J without pressing the knot M by hand. Since the ring R surrounding the self-hair J is restrained by the self-hair J, the position of the knot M is also maintained and can be pulled toward the tip side with respect to the knot M.
In the above, it is described that the third region G3 is first pulled toward the tip side to narrow the ring R surrounding the hair J, and then the second region G2 is pulled toward the tip side to narrow down the knot M. In the actual work, the hair extension G can be easily fixed to the desired position of the own hair J by pulling the second region G2 and the third region G3 toward the tip side at almost the same time.

Repeat steps 4 to 6 above until all hair extensions G are fixed to their own hair J. (Step 7). Then, the hair extension jig 2'is pulled out from the hair extension 20 of the hollow cylindrical member 4 and removed from the hair extension J (step 8).

As described above, the hair extension jig 2'to which a plurality of hair extensions G are attached by the artificial hair cut portion 10 can be attached to the user's own hair by using the own hair cut portion 20. Therefore, the operator can use both hands to form a knot of the hair extension G and to attach the hair extension G to the user's own hair J. Since the hair extension J is simply inserted into the notch of the hair notch portion 20, the hair extension can be easily attached to the user's hair without damaging the hair.

In particular, by adopting the knot M in which the third region G3 is passed through the ring of the single knot formed in the second region G2, the knot M of the hair extension G is formed by a simple operation. Since the ring R surrounding the hair J can be narrowed to narrow the knot M, the hair extension can be easily and efficiently attached to the user's hair J. Further, since only artificial hair is used, it can be attached to the user's own hair at low cost without damaging the own hair. Further, since the size of the knot M can be reduced, the extension G having a natural appearance can be realized.

Further, in the hair extension jig 2', a plurality of notches 12 for artificial hair are arranged side by side in the longitudinal direction of the hollow cylindrical member 4. As a result, many artificial hairs G can be efficiently arranged without hindering workability.
Further, when viewed from the longitudinal direction of the hollow cylindrical member 4, the artificial hair notch 10 and the self-hair notch 20 are arranged at an angle of approximately 90 degrees. As a result, it is possible to suppress the interference between the self-hair J attached to the self-hair notch 20 and the artificial hair G attached to the artificial hair notch 10 in the extension mounting work. As a result, the hair extension G formed of artificial hair can be efficiently attached to the own hair J.

In the above method of attaching the hair extension, the artificial hair is inserted into the cuts of the plurality of artificial hair notches 10 of the hollow cylindrical member 4 of the hair extension jig 2', and a knot M is formed by each of the inserted artificial hairs. After performing the work of making the extension G, the hair extension jig 2'is attached to the user's own hair J by using the cut portion 20 for the own hair, but the present invention is not limited to this. For example, a hair extension jig 2'in which artificial hair is inserted into the cuts of a plurality of artificial hair notches 10 may be attached to the user's own hair, and then a knot M may be formed with the artificial hair to form extension G. it can. In this case, for all the artificial hairs, after tying a knot M to form an extension G, the user's own hair J can be inserted into the ring R of each extension G and attached, or in each artificial hair. It is also possible to tie a knot M to form an extension G, and insert the user's own hair J into the ring R of the extension G to attach it.

(Method of adjusting the position of the hair extension according to one embodiment of the present disclosure)
When a plurality of hair extensions G are attached to the own hair J by the above method of attaching the hair extension, the own hair J is stretched, so that the attachment position of the hair extension moves to the tip side of the own hair J, which is unnatural. May show appearance. With the conventional method of binding artificial hair, it is difficult to loosen the knot of artificial hair once tightened. However, according to the method for adjusting the position of the hair extension according to one embodiment of the present disclosure, the knot can be easily loosened and the position of the hair extension attached to the own hair can be changed to a desired position. This will be described in detail below.

In the hair extension attached to the self-hair J as shown in FIG. 17, as shown by arrows X and Y, the second region G2 and the third region G3 are formed in the outward direction in which the narrowed knot M spreads. The knot M can be loosened by pulling to widen the ring R surrounding the hair J that was in close contact with the hair J (step 9). As a result, the ring R can be moved in the longitudinal direction of the hair J, so that the ring R surrounding the hair J is moved to a desired position in the longitudinal direction of the hair J (step 10). Then, by pulling the third region G3 extending from the knot M to the tip side toward the tip side with respect to the knot M, the ring R surrounding the hair J is narrowed and brought into close contact with the hair J, and the tip side from the knot M. By pulling the second region G2 extending to the tip side with respect to the knot M, the knot M is narrowed down so that the ring R surrounding the hair J is kept in close contact with the hair J, and the extension G is formed. It can be fixed to the hair J again (step 11).

Similar to the above method of attaching the hair extension, by pulling the second region G2 or the third region G3 from the extending direction of the own hair J in an angled direction, the tip side with respect to the knot M can be easily obtained. Can be drawn to. Further, by pulling the second region G2 and the third region G3 toward the tip side at almost the same time, the hair extension G can be easily fixed at a desired position of the own hair J.

As described above, by adopting the knot M in which the third region G3 is passed through the ring of the single knot formed in the second region G2, the easily narrowed knot M can be loosened and self-reliant. The hair J can be moved to a desired position in the longitudinal direction. Then, similarly to the above-mentioned method of attaching the hair extension, the hair extension G can be easily re-fixed to the own hair J by pulling the second region G2 and the third region G3 toward the tip side.
