Abstract
Abstract A permanent waving composition which imparts to the hair a substantially increased curl retention, as well as substantially improved hair manageability and improved hair feel and appearance, is attained by combining strong hydrogen bonding amino acids with a water soluble or emulsifiable silicone-based compound as additives to the basic permanent wave ingredients. By employing these two additives, a synergistic effect is achieved, with the resulting permanently waved head of hair possessing substantially increased curl retention, ease of manageability, and substantially improved feel and appearance. Preferably, the strong hydrogen bonding amino acids are formed from hydrolyzed silk protein.
