Abstract
In accordance with the present invention, there is provided a single-step process and composition of a category-2 hair bleach which can simultaneously lighten the hair up to seven levels, and effectively neutralize any undesirable warmth that accompanies the lightening process. This is achieved by including in the bleach composition disperse dye molecules which the present invention has found to be both, stable in the bleach, and capable of depositing the desired amount of various permanent tones on the hair. These disperse dyes do not stain the scalp of the client or the hands of the hairdresser, but are substantive only to the hair fibers. The dyes fall into the classes of anthraquinones and azo compounds.
