Description

  The present invention relates to a hair dyeing method, and more specifically, it can dye hair in various colors that cannot be expressed with a non-oxidative metal hair dye, and also suppresses fading of the dyed dye and maintains the color tone after hair dyeing. The present invention relates to a hair dyeing method that can be used.

Conventionally, as this type of hair dye, an oxidation type hair dye mainly composed of an oxidation dye such as paraphenylenediamine and hydrogen peroxide, and an acid type hair dye mainly composed of a direct dye such as a tar dye. And are commonly used.
However, in oxidative hair dyes, oxidative dyes cause skin allergies, and hydrogen peroxide has a very strong oxidative effect, which causes problems with hair damage and scalp irritation. Produce.
On the other hand, acidic hair dyes have the disadvantage that they are dyed not only on the hair but also on the skin such as the scalp and hands, and are discolored by shampoo, sweat, etc., and the fastness is insufficient.

In order to eliminate these points, many non-oxidation type metal hair dyes using polyvalent metal salts have been proposed (for example, see Patent Documents 1 to 5).
On the other hand, hair dyes such as color treatments are widely used because they can be used with bare hands without damaging the hair and scalp.
