Oxidized Keratin
What is Oxidized Keratin?
Oxidized keratin derives from natural keratin proteins found in animal hair, wool, or feathers, modified through oxidation processes like treatment with hydrogen peroxide. This alters its structure by breaking disulfide bonds, improving solubility and functionality for cosmetic use. Primarily featured in hair care products such as conditioners and shampoos, it also appears in skin care formulations. It works by forming a protective film on the hair shaft or skin surface, reducing friction, static electricity, and moisture loss. This surface-level action helps restore a smoother texture to processed or damaged hair and supports skin barrier function without deep penetration. Derived from renewable sources, it mimics the body's own proteins to provide a compatible conditioning effect in rinse-off and leave-on products.
