GlossaryCysteic Acid

compound formed when cysteine oxidizes, indicating hair damage

Cysteic acid is a compound that forms when the amino acid cysteine undergoes oxidation. In the context of hair, it can result from chemical treatments like bleaching or perming, which can damage the hair's protein structure. For professionals, it's important to note that the presence of cysteic acid indicates oxidative stress and potential weakening of the hair fiber.
