Abstract
The present invention relates to a hair treatment composition which provides an excellent finishing effect and superior protection against environmental, chemical, and grooming-associated damage. The compositions of the present invention comprise hydrolyzed protein having an abundance of anionic amino acids and in particular, sulphur-containing amino acids, as well as divalent cationic compounds, such that the anionic components of the hydrolyzed protein may effectively bind to the hair by means of cationic bridges. While bound to the hair, the sulphur containing amino acids in the hydrolyzed protein may serve as "decoys" for the effects of a variety of damaging agents. Compositions of the present invention may further comprise a vitamin compound which enhances these protective benefits.
