1. Hairstyling process comprising the following steps:
the application to the hair of a first cleansing cosmetic composition comprising one or more surfactants; the application of a second aqueous cosmetic composition comprising a vinylpyridine polymer, which is a neutralized non-crosslinked ethylenic polymer derived from the polymerization of: (A) from 5% to 100% by weight of a vinylpyridine monomer (Ia) and/or (Ib): (b) 0 to 95% by weight of at least one additional nonionic or cationic ethylenic monomer chosen from: optionally hydroxylated C1-12 alkyl (meth)acrylates; (meth)acrylamides bearing a group NH2 or NHR, R being a C1-C12 alkyl group, or NR1R2, R1 and R2 being a C1-C12 alkyl group such that the total sum of the carbon number of R1+R2 is less than or equal to 18; vinyl esters R′—COO—CH═CH2, R′ being a C1-C18 alkyl radical; vinyl ethers R″—O—CH═CH2, R″ being a C1-C18 alkyl radical; olefins, in particular C2-C20 alpha-olefins; vinyl alcohol, vinylpyrrolidone, vinylcaprolactam, N-vinylformamide, N-methyl-N-vinylformamide; N-methyl-N-vinylacetamide; vinyl butyral; vinyl carbazole; vinyl chloride; vinylidene chloride (or 1,1-dichloroethylene), cis-isoprene, trans-isoprene; vinylaromatic monomers containing from 8 to 20 carbon atoms and better still containing from 8 to 14 carbon atoms; and mixtures thereof; the polymer not containing any anionic monomer; said polymer being at least 10% neutralized; followed by a step of rinsing with water and then a step of shaping the hair, and then a step of drying the hair. |
