Abstract
Abstract A method of conditioning the hair and imparting semi-permanent hair set retention properties comprising treating the hair with a composition comprising a protein having a sufficient amount of an amino acid having a disulfide linkage, such as a keratin-based protein that includes the amino acid cystine. The method and composition are essentially pH independent and provide unexpectedly durable, semi-permanent hair set retention properties, and hair conditioning properties, after application to human hair.
