摘要： The present invention relates to hair fixative compositions which utilize as the hair fixative resin a polymer which is prepared from N-vinyl formamide (NVF). The polymer may be a homopolymer of NVF or an interpolymer of NVF and at least one vinyl monomer(s). The polymer is present in amounts effective to provide the inventive hair fixative compositions with hair fixative properties. In preferred embodiments, the hair fixative composition is a stable, aqueous gel which forms a clear, non-tacky film upon drying. In certain embodiments, the gel has a rheology effective to allow the gel to be applied to the hair via a spray pump.
