2. Description of the Related Art In recent years,
As consumers' awareness, there is a growing demand to gradually make black hair less noticeable naturally, or to make black hair lighter / change the nuances of the hair color. There is a type of hair dye on the market that contains acid dyes and can be used like a rinse to gradually add color to white hair. However, these types of hair dyes have a problem that the coloring effect is weak and it takes a considerable number of days to color to a satisfactory level. Further, the above-mentioned type of hair dye is usually adjusted to have a viscosity of 10,000 cps or more so that it does not drip to the scalp during the standing time. Therefore, if an attempt is made to enhance the coloring effect, the skin such as fingers will be colored during application, which will give an unpleasant impression to the user, which is not appropriate. Further, the coloring effect is increased by using a heating instrument such as far infrared rays or a steamer, but these are very laborious to carry out at home. Therefore, there has hitherto been no method of dyeing hair with a hair dye system containing an acid dye that gives a high coloring effect without contaminating the skin of fingers and the like.

Therefore, an object of the present invention is to provide a hair dye composition which is capable of obtaining a high coloring effect (hair dyeing effect) without soiling the fingers, and is excellent in the subsequent color retention, and the hair dye composition. It is to provide a method for dyeing hair by using.
