Description

[Technical Field]

[0001] The present invention relates to a hair dye composition used for dyeing hair. [Background technology]

[0002] Hair dye compositions containing dyes such as basic dyes and nonionic dyes are used to dye hair (for example, Patent Document 1 below). Hair dye compositions are sometimes used in the form of color shampoos that can dye hair at the same time as washing it, and color rinses (sometimes called color treatments or color conditioners) that can dye hair by applying the hair dye composition to washed hair.
