Hairdye compositions, in particular, acid hairdye compositions and oxidative hairdye compositions. The first characteristic of these hairdye compositions resides in that they have been thickened so that they remain stable and flowable, give an excellent texture in using and can easily washed away after being used even in a strongly acidic region (i.e., pH 1.5 to 4.0) wherein favorable hair dyeing effects can be achieved. The second characteristic thereof resides in that they have improved dyeing power and improved fasteness to sunlight and laundering, little damage the hair, can improve the hair gloss and have high storage stability. These advantages of the hairdye compositions can be achieved by incorporating therein succinoglycan which is a polysaccharide originating in microorganisms. |
