Description

  The present invention relates to a hair dye, and more specifically, by using it as a hair styling sensation, the hair is dyed gradually and without spots, and can be easily washed off with a shampoo or the like. It relates to hair dyes with low wearability.

Many hair dyes for dyeing white hair, decolorized and discolored hair to black have been proposed.
However, for example, when the gray hair suddenly changes to black, a sense of incongruity is generated and a different impression is given to others, so that it is desired to gradually become black so as to be as inconspicuous as possible.

  In order to meet such a demand, for example, a hair conditioner product containing a cationic surfactant, a fatty alcohol, a basic dye, and a neutral dye has been proposed (see, for example, Patent Document 1).

Moreover, the hair treatment agent containing a dimethyl silicone gum, a silicone oil, and a volatile silicone oil is proposed (for example, refer patent document 2).
Japanese Patent Publication No. 4-60566 Japanese Patent Publication No. 5-67122

  However, the former hair conditioner product is of the type that is rinsed with water immediately after the hair is treated with the product, and therefore, the action time on the hair is short, and as a result, the dyeing property to the hair is not always sufficient. It is difficult to say. Moreover, although the dyeing property to the skin has been improved to some extent, it is not yet satisfactory.

  On the other hand, the latter hair treatment agent imparts excellent slipperiness and gloss to the hair and protects the hair from heat and brushing of a dryer and the like, and is different from a hair dye.

  In view of the actual situation, the present invention allows the hair to be dyed easily and without spots by using it easily as a hair styling agent, and can be easily washed off with a shampoo or the like. The present invention provides a hair dye having a low dyeing property.

For example, if the hair is treated after bathing, it is washed off with shampoo at the next bathing time. Since it remains attached to the hair, the dyeing time is long, and therefore, the dyeing action can be effectively exhibited. On the other hand, the hair dye of the present invention can be easily washed off with a shampoo.

  Further, the hair dye of the present invention has a low dyeing property to the skin, and therefore it can be easily washed off even if it adheres to the skin such as the hand or face when it is processed into hair.
