About Cysteine

Cysteine is an amino acid.[1] In cosmetics, it is used to slow the rate at which formula ingredients oxidize through reaction with oxygen, reduce static that causes hair strands to lift or stick together, and reduce tangling and rough feel to leave hair smooth and manageable.[2] It is also used to help change the shape of hair in products that create waves or straighten hair, keep the characteristic odor or taste of raw materials from becoming too noticeable, and promote reactions that reduce other ingredients.[2]
