A process for treating keratin fibers comprising coloring said fibers with a coloring composition and then decolorizing them by applying a specific acidic aqueous composition

Abstract

The present invention relates to the field of cosmetic treatment of keratin fibers, preferably hair. It aims to provide a method for treating keratin fibers involving the bleaching of keratin fibers previously artificially colored by a coloring process using acetoacetate-type compounds and at least one pigment, by applying to said previously colored keratin fibers an aqueous composition (D) having an acidic pH and comprising at least one specific acidic agent.
