DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oxidative hair dye, and more particularly to an oxidative hair dye composition which gives a shine to hair and has an excellent conditioning effect.

[0002]

2. Description of the Related Art Conventionally, when dyeing hair, an oxidative hair dye has been generally used. As the oxidative hair dye, there is widely used a two-part type consisting of a first agent containing an oxidative dye intermediate and an alkaline agent and a second agent containing an oxidant, and mixing them at the time of use. Have been.

This oxidative hair dye allows a colorless, low-molecular-weight oxidative dye intermediate to penetrate into hair, and then oxidatively polymerizes the oxidative dye intermediate by the action of an oxidizing agent to produce a pigment.
By dyeing the dye in the hair, the hair is dyed, and the hair can be dyed in various colors as required.

[0004]

However, when a hair dyeing treatment is carried out using a conventional oxidative hair dye, the hair is inevitably damaged to some extent, and the hair may not be glossy or moist. This is due to, for example, oxidative degradation of hair cortex or keratin by an oxidizing agent.

[0005] In particular, in the case where the hair dyeing treatment is performed once and then the hair dyeing treatment is performed again due to fading or the like, the hair which has already been subjected to the hair dyeing treatment (the already dyed hair) is further damaged. However, there has been a problem that the gloss and moisture of hair are further lost. In order to solve this problem, conventionally, by adding an additive having a specific action to the oxidative hair dye, the feel of the hair has been improved to some extent or the gloss of the hair has been maintained. Was not sufficient, and it was difficult to simultaneously improve the feel and gloss of the hair. Furthermore, the effect of the additive may depend on the condition of the hair before hair dyeing, and depending on the condition of the hair, the above effect may not be sufficiently exerted.

[0006] The present invention has been made in view of the above points, and an oxidative hair dye composition capable of dyeing hair without causing damage to the hair and maintaining a smooth feel and luster of the hair. The purpose is to provide things.
