Description

  The present invention relates to a permanent wave forming device having a steam generation function and a permanent wave forming method, and in particular, to reduce the burden on the hair by quickly and easily penetrating a chemical solution into the hair, and to obtain a good wave. The present invention relates to a permanent wave forming instrument with a steam generation function that can be realized at low cost and a permanent wave forming method using the same.

  Conventionally, as a permanent wave forming method, a method of applying heat to the hair wound around a cylindrical rod from the outside using an infrared accelerator is generally used. In this method, since heat is applied to the hair wound around the rod from the outside, heat is applied from the upper part of the hair, and since the range of heat application is narrow, the time required for the treatment process is long and the wave is applied. In some cases, unevenness may occur or maintenance may be deteriorated. For this reason, permanent wave treatment agents with high pH are used in order to increase the waviness without cost, but such treatment agents with high alkalinity have an excessive burden on the hair, The damage received is great. Permanently treated hair is often damaged by hair treatments such as hair coloring and bleaching, and the current situation is that the population of permanent wave treatment is decreasing due to fear of further damage to hair. .

  Recently, as a new method for forming a permanent wave, a permanent wave forming device comprising a rod for a permanent wave having an electric heating means and a power feeder for feeding the rod and heating the rod by the heat generated by the electric heating means. Has been developed, and permanent wave processing using this instrument is becoming widespread. This rod was developed for the purpose of forming a firm wave in a short time by heating the rod itself by the heat generated by the built-in electric heating means.

  However, in such a permanent wave treatment, heat is directly applied from the rod to the hair wound around the rod, so that the hair is greatly damaged by the heat. In general, if the rod surface temperature is 40 ° C or higher for healthy hair, and the hair wound on a rod of 38 ° C or higher for bleached hair or damaged hair continues for 10 minutes or longer, the binding water contained in the hair will be insufficient. In addition, the protein component in the hair is altered. Moreover, it becomes easy to receive the damage by the influence of the chemical | medical solution for permanent waves. As a result, the moisture retention, flexibility, and smoothness of the hair surface are lost, and the physical properties and feel of the hair are deteriorated, such as the loss of hair luster due to loss of hairiness, splitting and cutting. There was a problem that good permanent waves could not be obtained in the hair. Furthermore, as the rod surface temperature becomes high, moisture is removed from the permanent wave chemical and the concentration of the chemical is excessively increased. As a result, the chemical becomes highly irritating enough to reach a dangerous level for the hair. There was also a problem that oxidation was promoted.

  The present invention has been developed in view of such problems, and a permanent wave forming device and a permanent wave forming device that can realize a good wave that is flexible and elastic while suppressing damage to hair at low cost. It aims to provide a method.

  As a result of intensive studies by the inventor in order to solve the above-mentioned problems, a sheet containing a permanent wave chemical and / or a water-containing rod (hereinafter also simply referred to as “electric rod”) in which electric heating means is incorporated. When a permanent wave treatment was performed using the same, a liquid component such as a chemical solution contained in the sheet became vapor and penetrated into the hair in a very short time, and the present invention was completed.

  That is, according to the present invention, there is provided a permanent wave forming device, which is a permanent wave forming device comprising a rod having an electrical heating means built therein and a hydrous sheet wound around the outer peripheral surface of the rod. The

  This permanent wave forming device is used for forming a permanent wave in a state where a chemical solution and / or water is contained in a water-containing sheet.

  The chemical solution and / or water contained in the water-containing sheet is converted into water vapor by the heat generated by the electric heating means, and the water vapor penetrates into the hair.

  In the permanent wave forming device provided by the present invention, it is preferable that the hydrous sheet is detachably attached to the rod.

  Further, according to the present invention, there is provided a permanent wave forming method, in which a hair-containing sheet containing a chemical solution and / or water is wound around a rod wound around an outer peripheral surface, and an electric heat generated in the rod. And a step of heating the rod with heat generated by the means and allowing the water contained in the water-containing sheet to form water vapor and permeate the hair. A method for forming a permanent wave is provided.

  In the present invention, the term “permanent wave chemical” or “chemical” means a permanent wave chemical containing components commonly used to form permanent waves, such as cysteine, thioglycolic acid, sodium sulfite, cysteamine HCL, and the like. Including those containing protein components used to protect the hair.

  According to the present invention, it is possible to quickly and easily infiltrate the hair with a low-perme chemical liquid component into the hair, so that the treatment time is shortened and the hair condition after the perm treatment is good with less burden on the hair. In addition, permanent wave processing with excellent wave formation has become possible. The present invention is effective for hair that has been damaged by hair cosmetics such as hair color, bleaching, curly hair straightening, and conventional perm, as well as healthy hair that is thick and thick, etc. Excellent effect on hair that is difficult to form.

  Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing one embodiment of a permanent wave forming device according to the present invention, in which a rod 12 incorporating an electrical heating means (not shown) and a water content wound around the outer peripheral surface of the rod 12 are shown. The sheet 11 is provided. The permanent wave forming device according to the present invention is used in a state where a permanent wave chemical and / or water is included in a water-containing sheet during permanent wave treatment, and the water-containing sheet 11 has an appropriate water retention capacity. If it is capable of evaporating liquid components such as permanent wave chemicals and / or moisture by heating and can be wound around the outer peripheral surface of the rod, it should be used without particular limitation, such as cotton and sponge. Can do. In addition, the shape, size and thickness of the hydrous sheet can be appropriately determined according to the length and amount of the hair to be subjected to permanent wave, the thickness of the rod, etc. The rod shape is also cylindrical, planar, etc. , And can be determined as appropriate according to the desired wave.

  In the permanent wave forming device 10 according to the present invention, the hydrous sheet 11 is wound around the electric rod 12, and the degree of winding of the sheet may be single or double or more with respect to the rod. . The means for attaching the sheet to the rod can be appropriately selected, and is preferably attached to the rod so as to be detachable with a double-sided adhesive tape or the like. 2 and 3 are explanatory views illustrating a process of attaching the water-containing sheet to the rod so as to be detachable. As shown in FIG. 2, a water-containing sheet 21 having a double-sided adhesive tape 24 at one end is provided. It may be attached by being wound around the rod 23, or may be attached so that the water-containing sheet 31 formed in a cylindrical shape in advance as shown in FIG.

  In the present invention, this water-containing sheet is used in a state in which a chemical solution is contained, and since there is no need to apply the chemical solution to the hair wound around the rod as in the prior art, the problem of dripping does not occur. On the other hand, in the case of including a step of applying a chemical solution to the hair during the treatment, a part of the applied chemical solution is once absorbed by the water-containing sheet and then vaporized and penetrates into the hair as described in detail below. Will be. Further, since the chemical solution component is uniformly permeated into the hair by being vaporized, the chemical solution component can be uniformly distributed to the hair without causing the problem of uneven coating of the chemical solution.

  The permanent wave treatment using the permanent wave forming device 10 according to the present invention is to change the chemical liquid and / or water contained in the water-containing sheet 11 into steam by the heat generated by the electrical heating means built in the rod 12. It is a characteristic, and the chemical liquid and water contained in the sheet wound around the rod are vaporized, whereby the chemical liquid components and / or moisture penetrates into the hair uniformly and in a short time. As a result, since the treatment can be completed before the air oxidation of the chemical solution proceeds, a permanent wave chemical solution having a pH of about 6 to 8 can be used, hair damage is small, and it does not spread even when dried. Flexible, elastic and firm wave formation is possible. Steam irons and steam brushes are on the market as hair devices with a steam generating function, but these are intended to set hair with heat while supplying moisture, The present invention is essentially different from the present invention having a steam generating function for vaporizing a chemical component for the purpose of rapidly penetrating hair into hair. Further, the steam iron and the steam brush generate steam from the provided holes, and it is difficult for the steam to spread uniformly over the entire hair. The generation mode is also excellent.

  FIG. 4 shows one aspect of the state in which the permanent wave forming device 40 of the present invention is connected to the power feeder 50. Electric power is supplied to the rod 42 by a power supply 50 connected by an electric wire 51 through a connector 43, and the surface temperature of the electric rod 42 is adjusted by controlling the heat generation state by an electric heating means (not shown). The The electrical heating means is not particularly limited. Permanent wave chemicals work most efficiently on hair because the temperature of the hair is around 36 ° C., which is the same as human body temperature, so in the permanent wave treatment using the permanent wave forming device of the present invention. It is preferable to adjust the surface temperature of the electric rod so that the hair temperature becomes that temperature (for example, about 36 ° C. as a guide). In the permanent wave treatment of the present invention, the generated water vapor quickly penetrates into the hair during the treatment, so water lost from the hair due to heating during the treatment is replenished, and the surface temperature of the electric rod is 45 ° C. or higher. In this case, it is possible to solve the problem of lack of moisture contained in the hair and alteration of the protein component in the hair, and it is possible to perform treatment at a temperature at which the drug solution works most efficiently. As a result, effective permanent wave treatment using a chemical solution having a low pH became possible in combination with an improvement in the permeability of chemicals and moisture to hair by vaporization.

  Furthermore, the generated water vapor not only supplies water to the hair, but also promotes the penetration of the permanent wave chemical solution, and also acts as a swelling component such as monoethanolamine contained in the chemical solution. (Thioglycolic acid, cysteine, etc.) Using a permanent wave chemical solution with a low content of about pH 6-8, in low temperature steam at about 35-40 ° C. and in a short time (eg, heating time of about 5-10 minutes) A good permanent wave can be formed.

  The effect of being able to suppress the use of alkaline agents and reducing agents (such as thioglycolic acid) contained in the permanent wave chemical solution is not only favorable for the hair and scalp, but also very favorable for safety. Until now, there have been products on the market that have a pH of around 6-8 and do not use strong alkaline agents such as thioglycolic acid or reducing agents. In reality, it was not so popular because it was bad, easy to be oxidized by air due to its low permeability, the number of rods used and the amount of chemicals used increased. It is possible to effectively use a chemical solution gentle to hair.

(Example)
EXAMPLES Hereinafter, although an Example demonstrates this invention in detail, the technical scope of this invention is not limited to these.

(Example 1)
Under the common conditions shown below, the wave states obtained when using the permanent wave forming method of the present invention and the permanent wave forming method other than the present invention were compared and examined.

[Common conditions]
・ Chemical solution: cystine agent (cystine 6% by mass, pH 7.5)
・ Rod: Diameter 22mm
-Treatment time: 10 minutes-Slice width: slightly thicker-Hair: healthy hair [Invention Example 1]
Permanent wave formation was performed using an electric rod in which a cloth sheet impregnated with the chemical solution was wound in a single layer and the surface temperature of the electric rod was 38 ° C. A firm wave was obtained even though a chemical solution (pH 7.5) having a low alkalinity was used and a thicker rod was used. Since cysteine has a large molecular weight of about 121, the permeability to hair is usually low, but it is presumed that the molecular weight was lowered by vaporization according to the present invention and the permeability to hair was increased. According to the present invention, it has been clarified that firm wave formation is possible using a low alkaline chemical solution having a pH of less than 8.

[Comparative Example 1]
A permanent electric wave was formed by applying a normal electric rod on which the water-containing sheet was not wound, setting the surface temperature of the electric rod to 38 ° C., and applying the chemical to the wound hair. The resulting wave was too loose.

[Comparative Example 2]
Permanent waves were formed by using a rod having no electrical heating means and applying the chemical solution to the hair using an infrared accelerator so that the hair temperature was 40 ° C. The resulting wave was too loose.

(Example 2)
As Example 2 of the present invention, permanent wave formation was performed under the same conditions as Example 1 of the present invention except that a sulfite containing sulfite as a main component was used instead of the cystine used in Example 1. Went. The obtained wave was as firm as Example 1 of the present invention using a cystine agent, and the condition of the hair was also good.

  The sulfite agent functions as a permanent wave chemical when heated, but its wave-forming ability is relatively weak, and the heat applied to it deprives the hair of the hair after treatment. In the present invention, since the chemical component and moisture permeate into the hair in a vaporized state at the same time as heat is applied, the permanent solution using a sulfite agent is used. It was revealed that even in the wave formation, good wave formation can be performed while suppressing hair damage.
