Keratin is used in a variety of hair and skin care products focused on boosting moisture in dry hair and helping improve elasticity and shine.

Keratin is a specialized protein found in hair, wool, nails, and even feathers that is used as a skin and hair conditioning agent. Acting as a humectant, keratin binds water to the surface of the skin or hair. The antioxidants found in keratin can help protect hair against visible signs of aging, strengthen the fibers, and improves elasticity. For color treated or damaged hair, it can help moisturize and restore shine, giving hair a soft, silky look. Used in skincare products, keratin can help aid the skin recovery process and is especially effective when used on dry skin, including the thick skin on hands and feet.
