Description

  The present invention relates to a hair pretreatment method and a hair pretreatment agent in hair cosmetic treatment.

  In a permanent perm for straightening hair and a perm for making hair into a wave shape, conventionally, a permanent first agent containing a reducing agent is first applied, rinsed, dried with a dryer, and heated at a high temperature of about 180 ° C. A method has been used in which hair is pinched with an iron, and then a permanent second agent containing an oxidizing agent is applied and oxidized. However, this method has a problem of causing hair pain.

  In order to solve this problem, a method of blending a conditioning agent in a permanent wave agent (Patent Document 1), a method of applying a conditioning agent as an intermediate agent after treatment of the permanent wave first agent and before application of the second agent (Patent Literature 2) Etc. are done.

  On the other hand, a method is also known in which the hair is wetted with water, dried, and the hair is sandwiched with a high-temperature iron of about 180 ° C. before applying the first permanent agent containing the reducing agent, and then the second permanent agent is applied. .

  However, these methods have a problem in that they are damaged when applied to unfavorable hair such as combed hair and dry hair generated with aging.

  The most common hair dye used for dyeing hair is a permanent hair dye that cannot be easily removed with shampoos, etc., and the first agent containing an oxidizing agent and an alkaline agent such as aqueous ammonia and an oxidizing agent. It consists of a second agent containing an agent. With such permanent hair dyes, it is possible to make the hair different from the original color by applying it to black hair or white hair, but the treated hair is not a little damaged, and the moisture retention of the hair is reduced, resulting in dryness. , Loss of luster and firmness, as well as split ends and cut hairs. In particular, the tendency was prominent for hair that became thin with aging.

  Furthermore, there is a method for treating hair damaged by the above-mentioned straight perm, perm, and hair dye. The mainstream of this treatment is that a feeling of repair can be obtained by adsorbing and penetrating fats and oils, cationic surfactants, etc. on the hair surface and inside. However, for hair that was thin with aging, it was not possible to maintain a style due to the weight of the adsorbed components, even if a feeling of repair was not obtained due to lack of moistness or a feeling of repair was obtained. .

Subsequently, an oxidative hair dye was applied to the hair bundle by the same method as in <Method 1 of applying oxidative hair dye>.

<Evaluation of leveling property of hair with oxidation hair>
About the hair bundle which performed each oxidative hair dyeing process performed in the said group VIII-group XI, visual evaluation was performed by 10 expert panelists about the leveling property of hair. The evaluation criteria are as follows, and it can be said that those having the evaluations of ○ and ◯ have good dyeing leveling.

◎: Eight out of 10 panelists are evaluated as being uniformly dyed ○: Out of 10 panelists, it is evaluated that 6 or more and 7 or less are uniformly dyed △: Of 10 panelists Among them, it is evaluated that 4 or more and 5 or less people are uniformly dyed. ×: Evaluation that 3 or less of 10 panelists are uniformly dyed <Other sensory evaluation>
Other sensory evaluations were performed with a straight-shaped permanent wave <Evaluation of softness of hair>, <Evaluation of moistness of hair>, <Evaluation of good touch of hair>, <Evaluation of good gloss of hair The evaluation was performed in the same manner as the evaluation of>.

<Evaluation of leveling of hair evenness>
Each hair bundle was washed with shampoo and dried with a dryer as one set. After the above evaluation, 5 sets were performed, and then the <evaluation of leveling of hair with oxidation hair> was evaluated again.

  The results are shown in Table 6.

  As shown in Comparative Example 99, the conventional method in which no hair treatment agent is used and no ironing treatment is performed, the flexibility, moist feeling, touch feeling, and gloss are very poor. On the other hand, since the hair used in this test was very fragile due to aging and its hair quality, the hair treatment agent No. 1 prepared in Production Examples 1 to 28 was used. Even in the case of using 1-28, the method without ironing did not change the flexibility, moist feeling, feel and gloss as in Comparative Example 99, or the difference was slight even when improved (Comparison) Examples 69-96). In addition, for the perishable hair used this time, even when the pre-ironing technique of ironing before the oxidative hair dye treatment is used, when the hair treatment agent is not used, the feeling of moisture and hand feeling The gloss was not different from that of Comparative Example 99, and the flexibility was only slightly improved, and the effect was not sufficient (Comparative Example 102).

  On the other hand, in Examples 57 to 84, a treatment with a predetermined hair treatment agent is performed before the oxidation hair dye treatment, and a pre-ironing technique is performed in which the iron is treated before the oxidation hair dye treatment. By combining, the flexibility, moist feeling, touch feeling, and gloss were all markedly improved from the x evaluation to two or more grades of ◯ or ◎ as compared with Comparative Example 99.

  Therefore, the above-mentioned effect obtained by combining the method of performing the treatment with a predetermined hair treatment agent before the oxidation hair dye treatment and the pre-ironing method of performing the iron before the oxidation hair dye treatment Greatly deviates from the expected range from the results obtained by performing these methods alone.

Comparative Examples 103-133
Hereinafter, a conventional hair treatment method in a damaged hair treatment process will be described.

<Method of applying hair treatment agent>
For each hair bundle prepared in <About the hair bundle used in the experiment>, first, 0.50 g of hair treatment composition Nos. 1 to 30 of Production Examples 1 to 28 and Comparative Production Examples 1 to 2 was applied to the whole hair bundle. A prepared hair bundle group (group XII) and a non-coated hair bundle group (group XIII) are prepared.

<Method 1 of applying treatment agent>
Apply 10g of treatment agent [Beta Layer Emulsion made by Little Scientist Co., Ltd.] to each group of hair bundles, and rinse with running water.

Examples 85-112, Comparative Examples 134-136
Hereinafter, the hair processing method by the treatment process performed by the Example and the comparative example is described.

<Method of applying hair treatment agent>
For each hair bundle prepared in <About the hair bundle used in the experiment>, first, 0.50 g each of hair treatment composition Nos. 1 to 30 of Production Examples 1 to 28 and Comparative Production Examples 1 to 2 is applied to the whole hair bundle. A hair bundle group (group XIV) coated and dried and a hair bundle group (group XV) coated with water instead of the hair treatment agent are prepared.

<Ironing process for hairdressing after application of hair treatment agent>
Next, before the treatment agent was applied, ironing was performed on each hair bundle in the same manner as in the above <Method for treating hair iron>.

<Method of applying treatment agent>
Subsequently, the treatment agent was applied to the hair bundle by the same method as in <Method 1 of applying treatment agent>.

<Evaluation of hair elasticity>
About the hair bundle which performed each treatment process performed in the said group XIII-group XV, sensory evaluation was performed by 10 expert panelists about the elasticity of hair. The evaluation criteria are as follows, and it can be said that those evaluated as ◎ and ○ have good elasticity of the hair.

◎: Eight out of 10 panelists rated it as elastic ○: Out of 10 panelists rated it as 6 or more and 7 or less △: Out of 10 panelists Evaluated that 4 or more and 5 or less people have elasticity ×: Out of 10 panelists, 3 or less evaluated as elasticity <Other sensory evaluation>
Other sensory evaluations were performed with a straight-shaped permanent wave <Evaluation of softness of hair>, <Evaluation of moistness of hair><Evaluation of the feel of hair>, <Evaluation of the glossiness of hair The evaluation was performed in the same manner as the evaluation of>.

<Evaluation of sustainability of hair elasticity>
Each hair bundle was washed with shampoo and dried with a dryer as one set, and after 5 evaluations were performed, <Evaluation of Elasticity of Hair> was evaluated again.
The results are shown in Table 7.

  As shown in Comparative Example 133, the conventional method in which no hair treatment agent is used and no ironing treatment is used, the flexibility, moist feeling, touch feeling, and gloss are very poor. On the other hand, since the hair used in this test was very fragile due to aging and its hair quality, the hair treatment agent No. 1 prepared in Production Examples 1 to 28 was used. Even when 1-28 was used, the method without ironing did not change the softness, moistness, touch, and gloss as in Comparative Example 133, but the difference was slight even when improved (Comparison) Examples 103-130). In addition, for the perishable hair used this time, even when using the pre-ironing method of ironing before the treatment treatment, if the hair treatment agent is not used, the moist feeling, feel, gloss As in Comparative Example 133, the flexibility was only slightly improved and the effect was not sufficient (Comparative Example 136).

  On the other hand, in Examples 85-112, by combining the treatment with a predetermined hair treatment agent before the treatment treatment and the pre-ironing method of performing the iron before the treatment treatment, a comparative example Compared with 65, the flexibility, moist feeling, touch feeling and gloss were all significantly improved from x evaluation to two or more grades of ◯ or ◎.

  Therefore, the above-mentioned effects obtained by combining the method of performing a treatment with a predetermined hair treatment agent before the treatment treatment and the pre-ironing method of performing the iron before the treatment treatment are obtained by combining these methods. This greatly deviates from the range that can be expected from the results obtained by performing alone.
