Abstract
Abstract Composition and process for treating keratinic substances with at least one anionic polymer and at least one quaternized protein. The invention concerns a process for the cosmetic treatment of keratinic substances and in particular hair, the skin or the nails, wherein at least one strongly cationic quaternized protein and at least one anionic polymer other than homopolymers of acrylic acid crosslinked by means of a polyfunctional agent or an amphoteric polymer are applied on the said substances.
