Abstract
Abstract A process for dyeing hair comprises in sequence applying to the hair an oxidation hair dye composition comprising a mixture of an oxidation dye, a cationic polymer and an oxidizing agent in an oxidation dye carrier, permitting said oxidation hair dye composition to remain in contact therewith for a time ranging from about 15-40 minutes, rinsing the hair with water, then applying to the rinsed hair a shampoo composition containing an anionic detergent and thereafter rinsing said hair with water.
