Composition intended for the treatment of keratin fibres, based on a cationic polymer and an anionic polymer containing vinylsulphonic groups

Process for the cosmetic treatment of hair, which comprises applying first a composition containing 0.01 to 10% by weight of at least one polymer containing one or more cationic groups and selected from a cationic or amphoteric polymer containing primary, secondary, tertiary or quaternary amine units or mixtures thereof and having a molecular weight of 1,000 to 5,000,000 and subsequently a composition containing 0.01 to 10% by weight of at least one anionic polymer containing vinylsulphonic units of the formula:

• ##STR23## in which M denotes hydrogen, an alkali metal or alkaline earth metal or an ammonium or amine group in a solvent medium which is water, a monoalcohol, a polyalcohol, glycol ether or a mixture thereof.
