Abstract

The present invention relates to a cosmetic composition comprising: one or more vinylformamide/vinylformamine copolymers comprising: from 10 to 95 mol % of units of formula A1, and from 90 to 5 mol % of units of formula A2, one or more cellulose-based thickening polymers; and one or more amphoteric or zwitterionic surfactants. It also relates to the use of this composition for shaping and/or fixing the hairstyle, to a cosmetic treatment process for the hair using said composition and also to a particular cosmetic set.
