Hair relaxer and post-relaxer hair brightener system

摘要

A hair relaxer and post-relaxer hair brightener system and method is disclosed which overcomes the undesirable alteration of the natural tone of hair, especially of naturally gray hair, by highly-alkaline hair-relaxing systems. The natural tone of such alkali-relaxed hair is desirably brightened, enhanced and restored in a hair brightening step by certain disclosed post-relaxer aqueous hair brightener compositions which contain an active hair brightening agent. In a particularly preferred embodiment, the hair brightening agent comprises a relatively low active concentration of hydrogen peroxide.
