Abstract
The present invention relates to hair care compositions which contain a polymer which is prepared from N-vinyl acetamide (NVAM) monomer and the use of those hair care compositions to treat hair. The polymer may be a homopolymer of NVAM or an interpolymer of NVAM and at least one vinyl monomer. The polymer is present in amounts effective to provide the hair care compositions with hair fixative properties and/or hair conditioning properties.
