A composition for the decoloration of dyed hair consists of an alkaline Composition A containing at least one reducing agent and having a pH-value between 7.5 and 12.5, and a Composition B stored separately therefrom until application, having a highly acidic pH-value of 1 to 4 and containing at least one oily or fatty substance, at least one water-soluble emulsifier and at least one perfume, being present as an emulsion. Both Compositions are admixed immediately prior to application, whereby a product with a pH-value of 2.5 to 5.0 is obtained. This product can be distributed evenly on the hair without dripping, has an agreeable smell by the perfume contained and stabilized in Composition B, and effects even decoloration of the dyed hair.

Composition and process for de-coloring dyed hair

A flowable pulverulent bleaching or dyeing composition for human hair with improved properties of use, particularly dustlessness and good miscibility with water or aqueous hydrogen peroxide solution, is obtained by addition, preferably by a melting or spraying process, of about 5% to about 30% by wt. of at least one wax compound having a melting point between about 40&deg; C. and about 130&deg; C., preferably a C,-C,-fatty acid mono- and (or) dialkanolamide, between about 40&deg; C. and about 130&deg; C. to a powder comprising at least one solid compound exerting bleaching activity upon application on human hair or at least one direct hair dye.
