Description

  The present invention relates to a hair dye composition which is excellent in dyeability and particularly excellent in washing resistance.

Hair dyeing has been practiced and established in a wide range of age, from gray hair dyeing to fashionable dyeing. The hair dye used mainly is a so-called hair dye that uses a combination of an oxidative dye and an oxidant.
Hair dyes are rich in color and have the advantages of being dyed well, brightly dyed, good color, easy to treat, etc., but also have drawbacks such as damaging hair and skin irritation such as allergies. .

So-called hair manicure using acid dyes and hair dyes using direct dyes (HC dyes, basic dyes, disperse dyes, etc.) do not damage hair for the purpose of eliminating the drawbacks of hair dyes as described above. It has been put on the market with a complaint of high safety.
However, the former is easy to dye on the skin and difficult to remove once it is dyed, so it is well established for professional use in hair salons and the like, but is not very popular for general use.
On the other hand, the latter has advantages such as low dyeability on the skin and high safety, but weak dyeability, deterioration of dyeability over time, prone to uneven dyeing, easy discoloration when washing hair, etc. In particular, the color fading during shampooing has not satisfied consumers.

  Patent Document 1 discloses a hair dye pretreatment composition containing a direct dye, glycine and / or taurine, and water.

  However, the pre-treatment composition for hair dye described in Patent Document 1 is used for pre-treatment of an oxidative hair dye to improve shampoo fastness of an oxidative hair dye used later. It does not improve the shampoo fastness of the pre-treatment agent composition itself. Furthermore, when using this pre-treatment composition for hair dyeing, treatment with the pre-treatment composition for hair dyeing, treatment with an oxidative hair dye, and two hair dyeing treatments are required. There is a problem that it is very troublesome.

  Further, the disadvantage of fading easily when washing hair is particularly remarkable when basic blue 99 is used as a dye, and there is nothing that satisfies consumers in this respect.
