Abstract: 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.
