Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a permanent method,
The present invention relates to a method for imparting permanent (permanent wave) to hair using a chemical solution.

[0002]

2. Description of the Related Art When a permanent is applied using a chemical solution, hair is partially wound around a rod having an appropriate diameter, and then the rod is fixed to a head with a rubber band or the like, and the entire area of the hair to be permanent is applied. After that, apply a chemical solution (first perm solution) from above the head to the perm target area, and cover the back of the head with a towel turban from the forehead so that the chemical solution does not drip onto the face or the like. I have to. After a lapse of a predetermined time, the second perm solution is applied in the same manner as the first perm solution, and then the hair is washed and finished.

A conventional permanent rod is made of a plastic cylinder, and the applied chemical liquid permeates and fixes the hair while flowing along the hair itself and the surface of the rod. In order to make the fixation more uniform, a slit is formed in the rod or the rod is formed in a mesh shape, so that a hole is formed in the rod so that the chemical solution can reach the hair part on the scalp side through the inside of the rod, for example. ing.

[0004]

However, in the permanent method using a conventional rod, as described above, the chemical solution is permeated and fixed on the hair by utilizing the flow of the chemical solution through the hair itself or the rod. Therefore, the application amount of the chemical solution is increased to ensure the fixation of the chemical solution to the hair and equalization thereof, but about 1/2 of the applied amount is absorbed by the towel turban. It is actual and wasteful.

In addition, when a rod having a large diameter is used, the height difference between the hair portion on the scalp side and the outer side (irregularities due to the rod) increases, and the flow of the chemical solution also increases, and the chemical solution flows to the hair. Retention rate drops. Therefore, when a large and gentle wave hair style that is currently popular is finished with a large-diameter rod, it cannot be reliably finished even if a normal chemical is used. However, in such a case, adverse effects such as fading of the hair color and damage to the hair or the scalp occur, and as a result, the perm does not last long or the maintenance afterwards becomes difficult.

Furthermore, the most severely damaged bristle tip generally penetrates into the perforation of the rod when winding the rod, causing the hair to break or tear.

Furthermore, in order to improve the fixation rate of the chemical solution to the hair, a method has been practiced in which, when the hair is wound around a rod, paper having a liquid absorbing property is wound together.
In order to spread the chemical on all the papers, the applied amount of the chemical can hardly be reduced as compared with the case where no paper is used.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to make it possible to surely fix a minimum necessary chemical solution to hair and to prevent damage to the hair itself and the scalp. It is to provide a permanent method that cannot be given.

Another object of the present invention is to provide a permanent method which is particularly suitable for permanent waves having large and gentle waves.

[0010]

The rod used in the permanent method according to the present invention is a sponge-like and cylindrical outer shell capable of containing a chemical solution for the permanent, and a core for supporting the outer shell. And a liquid-impermeable rod body that does not allow the chemical solution to pass or absorb.

The rod body is a hollow cylindrical body or a solid cylindrical body capable of providing a sponge-like cylindrical outer body with a predetermined shape from the inside, and has a small rod diameter. Excluding the cost and weight, it is preferable to use a hollow cylindrical member from the viewpoint of cost and weight.

[0012] Therefore, the inner surface of the outer cover is made to substantially contact the outer surface of the rod body.

Further, it is desirable that both ends of the rod body carry not only a role as a core of the outer skin but also a role as a grip portion for winding the hair and a portion provided for fixing with a rubber band or the like after winding. Therefore, it is preferable to remove both ends of the rod body from the covering of the outer cover.

The outer shell and the rod body may be inseparable from each other, but by making them detachable, for example, even if the outer shell is damaged, only the outer shell is replaced and the rod body can be used as it is. Advantages such as dispersion of durability can be obtained.

The material of the outer skin may be any material that can hold a chemical solution such as polyurethane or polypropylene and release the held chemical solution to the hair through contact and allow penetration and fixation.

As the material of the rod body, the same material as that of the prior art such as acryl styrene can be used.

Further, the liquid-impermeable property of the outer surface of the rod body, which does not allow passage or absorption of the chemical solution, means that the rod body allows the chemical solution to pass from the outer surface to the inner side through the perforation, or the inner surface to the inner surface from the outer surface. This is not intended to be absorbed into the side. Therefore, when the rod body is a hollow cylindrical body, a hole such as a slit provided in a conventional rod is not provided in the rod body.

In this case, the chemical contained in the outer skin does not go to the inside of the rod body at all, but only to the hair portion wound around the outer skin.

The permanent method according to claim 1 of the present invention is a permanent method using the above-mentioned permanent rod, wherein the permanent liquid is applied to the outer skin prior to the step of winding the rod around the hair. It is characterized by being included.

That is, instead of applying a chemical solution after the hair has been wound around the rod as in the prior art, the hair is wound around a rod having the outer skin body containing the chemical solution. As a result, the chemical solution can be permeated and fixed from the outer skin to the hair wrapped around it without flowing, so to speak, the outer skin serves as a support for the penetration and fixation of the chemical to the hair.

Further, a perm method according to a second aspect of the present invention is a perm method using a perm rod composed of the above-mentioned outer body and a rod body, wherein the outer body contains a perm chemical. It is characterized by including a step of wetting the outer shell with water prior to the step.

[0022] This is because when the outer skin of a polyurethane foam is moistened with water and then a chemical solution is added to the outer skin, the absorption and retention of the drug solution by the outer skin become better than that of a dry outer skin. Was. Therefore, a chemical solution is included in the outer skin body that has been moistened with water, and the process of applying a permanent in such a manner can be divided into the following three modes.

A) A step of wetting the outer shell with water (by soaking the outer shell in water and then slightly squeezing) → a step of including a chemical solution in the outer shell → a step of winding a rod b) a step of winding a rod → Wet the outer skin with water (eg, by spraying) → Include the chemical in the outer skin (apply the chemical from above) c) Wet the outer skin with water → Wind the rod → Step of Including Chemical Solution in Outer Body Note that the above step a) substantially depends on the method according to claim 1 and enjoys various effects obtained by the method.

In the methods (b) and (c), the chemical applied from above the head is favorably retained and absorbed by the outer skin, so that the amount of applied chemical is significantly smaller than in the conventional method.

[0025]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a rod 10 used in the present invention.
(See FIG. 2) and a plastic rod body 12 (see FIG. 3). The outer shell 11 and the rod main body 12 are both cylindrical, and the outer shell 11 is detachable from the rod main body 12, and covers the outer surface of the rod main body 12 except for near both ends at the time of mounting.

The rod body 12 is gradually reduced in diameter from both ends to the center so that the mounted outer body 11 is not accidentally detached, and has small irregularities (not shown) on its outer surface as a non-slip surface. Is provided. The rod body 12
Is not provided with a perforation such as a slit, and the outer surface of the main body has liquid impermeability that does not allow a chemical solution to pass or absorb into the inside. A plurality (eight) of notches 13 for stopping rubber bands are provided at both ends of the main body at equal intervals in the circumferential direction.

Next, a method of using the rod 10 will be described.

First, the outer shell 11 attached to the rod body 12 is moistened with water, and then contains a required chemical (first permanent liquid). This is a bat (not shown)
Is placed under the container, the chemical solution contained in the container (not shown) is contained in the outer shell 11 through the nozzle, or a predetermined amount of the chemical solution is put in the vat in advance, and the rod 1
For example, 0 is rolled in the bat.

Next, after the hair is wound around the rod 10, the rod 10 is fixed to the notches 13 at both ends of the main body by scratching a rubber band. This is performed over the entire hair portion to be permed.

At this time, the chemical held by the outer shell 11 does not flow toward the inside of the rod body 12 and hardly flows down to the scalp, face, etc.
Gradually and surely penetrates and settles into the hair wound around it.

Thereafter, finishing is performed through conventional steps.

Even if the chemical is applied from above the head after the outer body 11 has been moistened with water and the rod 10 has been wound, the absorption and retention of the chemical in the outer body 11 is good. The amount of application can be reduced.

[0034]

As described above, in the permanent method according to the present invention, the chemical solution can be directly penetrated and fixed from the sponge-like outer skin containing the chemical solution into the hair directly. The fixation rate of the hair on the hair is significantly improved compared to the conventional method, and at this time, the chemical liquid does not pass through and is absorbed from the outer surface of the rod body to the inner side. It is possible to reliably fix.

In addition, it is possible to reliably apply a large and gentle wave permanent with a normal chemical solution instead of a strong chemical solution as in the prior art, without damaging the hair itself or the scalp. .

Furthermore, for a person with fine hair or a small amount of hair, if the hair is wound around the root with a rod, the rod may press the scalp, causing pain or sticking to the back of the rod. However, in the present invention, since the sponge-like outer skin plays a role of cushioning or protecting the scalp, the above-mentioned adverse effects are eliminated.

Furthermore, if the hair tips do not penetrate into the hole of the rod and damage the hair tips as in the prior art, for example, if a treatment agent such as PPT is applied to the outer skin,
Unnatural waves only at the tips of the hairs can be avoided.
