摘要

The present application relates to a process for the cosmetic treatment of keratinous fibers, in particular human keratinous fibers and more particularly to hair, characterized in that it comprises at least the two following stages: a first stage of application on keratinous fibers of a composition comprising one or more cationic polymers then, a second step of applying to said keratinous fibers a composition containing one or more zwitterionic fatty-chain surfactants, the surfactant (s), zwitterionic active (s) being such that at least 50% by weight of them have at least one fatty chain having a number of carbon atoms equal to or greater than 14.
