Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic composition, and more particularly, it has a hair dyeing effect, has excellent hair styling properties, and is dyed with repeated use. The present invention relates to a hair cosmetic composition having an improved hair effect. 2. Description of the Related Art
Products that address the concerns of gray hair include permanent hair dyes using oxidation dyes, semi-permanent hair dyes such as hair manicures and color rinses using acid dyes, and temporary hair dyes using pigments. I have. Also, as a product especially targeted at men, a hair styling product combining a hair styling function and a temporary hair dyeing function to make gray hair inconspicuous, for example, an aqueous gel base mixed with a pigment or the like, or an oily pomade base as a dye And the like are also known. [0003] However, although these hair styling materials have a hair dyeing effect, all have only a temporary hair dyeing function.
If the hair was washed, the effect would be lost.
In addition, since the base of these hair styling materials is highly adhesive such as water-based gel or oily pomade, it can be accepted by relatively old generations even among middle-aged and elderly people, but hair styling materials such as hair liquids are less sticky. There was also a problem that it was hard to accept for generations who use. [0004] On the other hand, when it is intended to make gray hair inconspicuous by using a hair styling agent in which a dye is directly added to the hair liquid base, it is necessary to use a large amount of a dye compound. Migrating problems arise. In addition, since the color rinse is applied to the hair, and is used after being left and washed off, there are disadvantages such as dirty hands and complicated operation. As described above, there has been no known hair styling material which is non-greasy, has excellent hair styling properties, and has an effect of making gray hair less noticeable. [0005] Under such circumstances, the present inventors have conducted intensive studies and as a result, have found that they contain a polyoxyalkylene derivative, a specific organic solvent and a direct dye, and are adjusted to a specific buffer capacity. It has been found that the obtained hair cosmetic composition is excellent in hair styling power without stickiness, and that the hair dyeing effect is improved as it is repeatedly used, thereby completing the present invention. That is, the present invention provides the following components (A) to
