ABSTRACT:
The present invention relates to a 2-step methods, and compositions for providing more vibrant, natural and long-lasting color to hair and at the same time reducing hair fiber damage associated with alternative current methods. In the first step the hair is contacted for a period of time with a dye precursor mixture containing specific oxidative hair dye precursors under conditions where these dyes are substantially inactive. Color is then developed in a second step by contacting the hair with a mixture of a peroxide compound and a persulfate salt. Surprisingly the 2-step method leads to considerable “lift” or lightening without negatively impacting the coloring ability of the oxidative dye. The invention also relates to kits providing the means to accomplish these steps.
