Description

  The present invention relates to a three-part hair treatment agent comprising a first agent, a second agent, and a third agent that are sequentially applied to hair. The three-component hair treatment agent of the present invention can be used as a hair rinse agent, a hair treatment agent or a hair conditioning agent.

  The daily shampoo treatment causes the oil necessary for the hair to be washed away more than necessary together with the dirt on the hair, or the hair is damaged by drying the dryer, and the hair is damaged daily. In addition, with recent spread of decolorization treatment, hair dyeing treatment, perm treatment, etc., hair damage is becoming more prominent. For example, due to a decrease in luster due to a decrease in moisture content, loss of smooth texture, and increased feeling of dryness, not only the flexibility and fingering properties of hair deteriorate, but also split ends and tears are more likely to occur. .

  In order to eliminate such hair damage, components such as cationic surfactants, cationic polymers, silicones, and cationic silicones are usually used as hair treatment agents such as hair rinses, hair treatment agents, and hair conditioning agents. (For example, refer patent documents 1-6).

  However, since many hair rinse agents, hair treatment agents, and hair conditioning agents are oil-in-water emulsions, oily components such as treatment components are in a state of being taken into water. Therefore, these hair treatment agents do not adhere well to the oily components due to differences in the surface condition of the hair, so that the hair feels soft and easy to touch and improves the appearance of moisture and luster. It is not possible to obtain a sufficient effect. There is also a problem that these effects are inferior in sustainability.

(Test example: Evaluation of treatment effect)
About the hair bundle immediately after the process by Examples 1-6 and Comparative Examples 1-6, according to the following evaluation criteria, the flexibility, fingering property, touch feeling, moist feeling, and glossiness were evaluated by 20 professional panelists. Moreover, the shampoo process was repeated 5 times with respect to the hair bundle after a process, and 20 expert panelists evaluated similarly to the hair bundle immediately after a process. These results are shown in Table 4. In addition, in order to understand easily, each processing process of Examples 1-6 and Comparative Examples 1-6 was put together in Table 3.

<Flexibility evaluation criteria>
Number of panelists evaluated as more flexible than the test hair bundle ◎: 16 or more, ○: 11 to 15, △: 6 to 10 people, ×: 5 or less

In addition, it can be seen that the hair immediately after the treatment is excellent in flexibility, fingering, touch and moist feeling, and that the hair is given a moderate gloss. Moreover, when the 1st agent, the 2nd agent, and the 3rd agent are applied sequentially (Examples 1-6), when the liquid mixture of the 1st agent, the 2nd agent, and the 3rd agent is used (comparative example 6). It can also be seen that the above effects are superior. Furthermore, in Examples 1-6, it turns out that an effect remarkably continues rather than Comparative Examples 1-6.
