Description

  The present invention relates to a hair thickening method and a hair thickener used in this hair thickening method, and more particularly to a device for directly adhering artificial hair to the scalp.

  A wig is known as a method of covering thinning hair and hair loss. Wigs are made by implanting artificial hairs on the wig base, and many hairs can be placed on the head at the same time, but depending on the type of wig base, it feels like an object is placed on the head. Some people feel uncomfortable when they receive it.

  One method that does not cause a feeling of wearing or discomfort is the hair thickening method. For example, in Patent Document 1 (Japanese Patent No. 2549565), a method of increasing the number of false hairs by branching a plurality of artificial hairs to one self hair by adhering false hairs to the remaining own hair with hot melt. Has proposed. In Patent Document 2 (Patent No. 3877533) and Patent Document 3 (Japanese Patent Laid-Open No. 2006-225828), a plurality of artificial hairs are implanted on a small substrate, and this substrate is adhered to the scalp with an adhesive. Proposed method.

  However, the thing of patent document 1 has the problem that it becomes easy to remove | eliminate the whole own hair, since a burden is applied to the own hair which adhered the artificial hair. Moreover, it cannot be applied to a place where there is no self hair.

  The methods of using small substrates described in Patent Documents 2 and 3 are easier to use as the substrate is smaller. However, when the substrate is small, there is a problem in that the number of times of application increases and workability deteriorates. In addition, hair cannot be implanted on the entire surface of the substrate, and there is no hair transplantation around the substrate, but this substrate remains on the scalp after thickening, so the smaller the substrate, the higher the percentage of this hairless part. There is also a problem that the density of flocking cannot be increased.

  The present invention has been made in view of such circumstances, and it is possible to increase the hair with a desired density without giving a feeling of wearing, without giving a burden to the own hair, and this hair increase method with excellent workability, and this hair increase It aims to provide a hair thickener for use in law.

  In order to achieve the above object, the hair thickening method of the present invention includes a step of flocking artificial hair having an adhesive edge on a base material that dissolves in a specific solvent in a state where the adhesive side is locked to the base material, A step of forming an adhesive layer with an adhesive that does not dissolve in the solvent on the side where the artificial hair is bonded, a step of applying the base material on which the artificial hair is implanted to the scalp using the adhesive layer, and an attachment to the scalp And a step of dissolving the prepared substrate with a solvent.

  The step of forming the adhesive layer may be formed on the base material before the step of locking the artificial hair to the base material, or the base material is a flexible sheet-like base material, The step of locking the artificial hair to the base material and planting the hair is configured to be a step of penetrating both ends of the artificial hair at two spaced locations of the base material, or the base material is in the form of a thread, The step of locking the artificial hair to the base material and implanting the hair can press the end portion or the intermediate portion of the false hair against the base material and bend it to form an adhesive side and lock it to the base material. .

  In order to achieve the above object, the hair thickener of the present invention is characterized in that artificial hair having an adhesive edge on a base material soluble in a specific solvent is implanted so that the adhesive side is locked to the base material. It is said. It can be set as the structure which fixed the said adhesion side and the said base material with the adhesive agent which does not melt | dissolve in the said specific solvent.

  According to the hair thickening method of the present invention, since the base material is not dissolved by the solvent, there is no feeling of wearing, and there is an excellent effect that the hair can be thickened without imposing a burden on the own hair. In addition, since a large number of artificial hairs are implanted in advance on the base material, they can be collectively fixed to the scalp, so that a desired density can be obtained and workability is improved.

It is the figure which has applied the scalp protection agent to the scalp of the head. It is a figure which shows the state which planted the artificial hair to the base material, (a) is a perspective view of a base material, (b) is a perspective view which shows the state which transplanted, (c) is the BB sectional view of (b). FIG. (a) is sectional drawing of the hair growth tool which planted the artificial hair in L shape, (b)-(f) is a perspective view which shows another aspect of an adhesion side. It is a figure which shows the state immediately before sticking a hair growth tool on a scalp. It is a figure which shows the state which affixes a hair thickener on a scalp. It is a figure which shows the state which stuck the hair thickener on the scalp. It is a figure which shows the state which wash | cleans the head which attached the hair thickener with water. It is a figure which shows the state which only the artificial hair adhered to the scalp. (A)-(d) is the figure which expanded the part of the adhesion side of pseudo hair. It is a figure of the Example using a thread-like base material.

  FIGS. 1-8 is a figure explaining the Example of the hair thickening method of this invention. FIG. 1 is a diagram in which a scalp protecting agent 10 is applied to the scalp of head A. Thereafter, the artificial hair is fixed to the scalp with an adhesive. This is to prevent the adhesive from coming into direct contact with the scalp, depending on the person whose hair is increased, such as when the scalp is roughened by the adhesive. This process is not an essential process because it is unnecessary for some people. As the scalp protecting agent, an acrylic polymer, a medical wound dressing material, a skin film agent or the like can be applied in the form of a sheet, or a gel can be applied.

  FIG. 2 is a view showing a state in which artificial hairs 12 are implanted in the base material 11, (a) is a perspective view of the base material 11, (b) is a perspective view showing a state in which hair is implanted, and (c) is (b) It is a BB line sectional view of). The base material 11 is made of a material that can be dissolved by a special solvent, and is soft and sheet-like. In the examples, the water-soluble substrate 11 is used, but the solvent other than water is not particularly limited as long as it has a small influence on the scalp such as ethyl alcohol, citric acid, and acetic acid.

  Here, “soluble in a solvent” literally includes not only a case where it is soluble in a solvent such as water, but also a state where, for example, Japanese paper is decomposed into fibers by water and the sheet cannot be maintained. .

  As shown in (a), the substrate 11 is transparent or translucent, and has an adhesive layer 13 formed in a dot shape on the back surface. As shown in (b), artificial hairs 12 are implanted into the water-soluble sheet-like base material 11. As a method of flocking, for example, first, the one end 12a of the artificial hair is pierced from the point 11a on the upper surface of the base material 11 and penetrated to the lower surface. And it draws out to the lower surface long, and leaves the length to the other end 12b about 1/2 of the artificial hair. When the one end 12a of the artificial hair protruding from the lower surface is folded, penetrated from the lower surface to the upper surface at a point 11b on the lower surface of the base material 11, and drawn out to the upper surface, the artificial hair 12 becomes U-shaped as shown. The bottom side 12c of the U-shaped artificial hair 12 remains on the adhesive layer 13 on the lower surface of the base material 11. The bottom side 12c is an adhesive side that adheres to the scalp by the adhesive layer 13. Since the length of the bonding side 12c is related to the bonding area between the artificial hair 12 and the scalp, it is sufficient that the longer one can increase the adhesive force. However, if the length is too long, the hair cannot be implanted at a desired position on the scalp. It should be shortened because it increases the nature. In this invention, it is 1-3 mm.

  Similarly, a large number of artificial hairs 12 are implanted in the base material 11. At this time, if the base material 11 is made of a transparent or translucent material, the hair can be implanted while checking the position of the adhesive layer 13 on the back surface. When the flocking is completed, the hair thickener 15 is completed.

  The method of flocking in the above embodiment is an example. In short, any method may be used as long as both ends of the artificial hair can be inserted into two spaced apart portions of the base material to form a U shape. Moreover, in the said Example, although the timing which forms the adhesive bond layer 13 is after formation of the base material 11 and before flocking, it may be just before sticking to a scalp after flocking.

  The adhesive used for the adhesive layer 13 needs to be able to fix the artificial hair 12 to the scalp with sufficient strength by adhering the bonding edge 12c of the artificial hair 12 to the scalp. In addition, it must be insoluble in the solvent that dissolves the substrate 11. In this embodiment, since the substrate 11 is water-soluble, an adhesive that does not dissolve in water is used. Moreover, it is necessary not to harden | cure before adhering to a scalp, and an adhesive is desirable. As such an adhesive, for example, N-alkyl-substituted acrylamide, (meth) acrylate, and the like can be used. From the viewpoint of irritation to the skin, a silicone-based adhesive is desirable. Moreover, since it is an adhesive, it is good to cover with the release paper after forming the adhesive bond layer 13.

  In the embodiment shown in FIG. 2, since the adhesive side 12 c is in the middle of the false hair, the adhesive side 12 c is locked to the base material 11 regardless of the presence or absence of the adhesive layer 13. Therefore, the adhesive layer 13 may be formed after the artificial hair 12 is implanted, for example, immediately before adhering to the scalp. In this case, the hair thickener 15 is obtained by implanting the artificial hair 12 on the base material 11 without the adhesive layer 13. As the adhesive in this case, for example, the above-mentioned pressure-sensitive adhesive or Dermabond (registered trademark) can be used.

  In order to increase the density of flocking, an adhesive can be applied to the entire lower surface of the substrate 11, or, in contrast to the embodiment shown in the figure, a portion where no adhesive is applied can be provided in a dot shape. Also in this case, the adhesive application time does not matter before and after flocking.

  FIG. 3 is a diagram showing another embodiment of the bonded side. In the embodiment of FIG. 2, the artificial hairs 12 are implanted in a U shape, but as shown in FIG. 3A, even if the U shape is divided in half at the bottom, Good. In this case, the bottom side of the L-shaped artificial hair 12 becomes the adhesive side 12c1. Further, the adhesive side 12c2 is formed in a ring shape as shown in FIG. 3B, the adhesive side 12c3 is made triangular as shown in FIG. 3C, or the V-shaped adhesive side 12c4 is shown in FIG. 3D. Various shapes such as an adhesive side 12c4 composed of an annular portion and a rod-like portion having a diameter as shown in FIG. 3E, or an N-type adhesive side 12c6 as shown in FIG. 3F. Can be. By doing in this way, an adhesion area can be enlarged.

  In the case of FIGS. 3A, 3B, 3C, and 3D, the adhesive sides 12c1, 12c2, 12c3, and 12c4 are connected to the pseudo hair 12 only on one side, so that the adhesive side is adhesive or the like. It is necessary to lock to the base material 11. In this case, the adhesive layer 13 may be used as the adhesive, but an adhesive different from the adhesive layer 13 may be used. In the case of FIGS. 3E and 3F, the bonding sides 12c5 and 12c6 are connected to the artificial hair 12 at both ends, and need not be bonded and fixed. In these embodiments, the bonded side is an extension of the artificial hair 12, but the bonded side may be formed from a different material from the artificial hair 12 and bonded and fixed to the artificial hair 12.

4 to 8 show a state in which the hair thickener is attached to the scalp. As the hair thickener used here, any of the bonding edges shown in FIGS. 2 and 3 may be used.
FIG. 4 is a diagram showing a state immediately before the hair thickener 15 is applied to the scalp. Since the hair thickener 15 is obtained by implanting a large number of artificial hairs 12 on a base material 11 having a predetermined shape and size, it may not match the shape of the hairless part of the scalp to be applied. In that case, the hair thickener 15 formed in advance can be used by cutting it according to the shape of the portion of the scalp where the hair is planted. Since it is used in this way, the hair thickener can be formed in advance using a fixed shape such as a rectangle.

  FIG. 5 is a diagram showing a state in which the hair thickener 15 is applied to the scalp. After applying the hair thickener 15, the adhesive layer 13 on the bottom 12c of the back surface of the base material 11 is pushed from the surface of the base material 11 with a spatula 16 to ensure adhesion between the scalp and the artificial hair 12.

  FIG. 6 is a diagram showing a state in which the hair thickener 15 is attached to the scalp. Thereafter, as shown in FIG. 7, when the head is washed with water (warm water), the water-soluble base material 11 is dissolved and disappears, and the adhesive layer 13 remains insoluble in water, as shown in FIG. Only the artificial hair 12 is adhered to the scalp. The hair thickening work of the present invention is now complete, but after this, the hair and artificial hair 12 are further cut to obtain an appropriate hair style.

  In addition to rinsing with water, the substrate 11 may be naturally extinguished due to sweat or the surrounding environment even if it is left as it is when it is attached to the head. Furthermore, it is also possible to add a component having a hair-restoring effect to the adhesive constituting the adhesive layer 13 so that the hair can be nourished at the same time as the hair increase.

  FIG. 9 is an enlarged view of the bottom side 12 c of the pseudo hair 12. (A) is the artificial hair shown in FIG. 2, and the base 12c is the same as the other part and has a circular cross section. (B) is an example in which the bonding area 12c ′ as a base is deformed zigzag in a direction perpendicular to the scalp to increase the bonding area. (C) is an example in which the bonding side 12c ″ is deformed flat and is elliptical as shown in (d) to increase the bonding area.

  FIG. 10 is a diagram of an embodiment in which a thread-like base material 21 is used. The substrate 21 is made of a material that is soluble in a special solvent such as water solubility. In the illustrated embodiment, the cross-sectional shape of the substrate 21 is circular, but it may be any cross-sectional shape such as a triangle, a quadrangle, or an ellipse.

  The center of the artificial hair 12 is folded back to the base material 21 as shown in FIG. For example, the locking method may be temporarily fixed with an adhesive having a weak adhesive force. The U-shaped base 12c is an adhesive side. The adhesion side 12c can be changed to any one of the adhesion sides 12c1 to 12c6 in FIG. Although only one artificial hair is depicted in the figure, a large number of artificial hairs are similarly locked. And it presses and press-contacts to the sheet-like adhesive bond layer 23 previously formed as shown in (b). Then, as shown in (c), the adhesive layer 23 is cut along both side portions of the base material 21 to complete the hair thickener 25.

  Even when this hair thickener is used, the substrate 21 is adhered to the scalp with the adhesive layer 23, and then the base material 21 is dissolved with a solvent such as water (warm water) and washed away.
