Abstract
The invention is directed to a three-part bleaching composition and method comprising pigments in a third composition. It has unexpectedly been found that an third composition comprising pigments increase the contrast between bleaching composition and keratin fibers to a degree which allows for a more accurate judgement of the desired end point of bleaching during the bleaching process.
