Hydrolyzed Keratin Protein is a protein derived from keratin, a fibrous structural protein naturally present in hair, skin, and nails. Through hydrolysis, the keratin is broken down into smaller peptides or amino acids, making it water-soluble and easily absorbed. This form is widely used in cosmetic and hair care products to repair, strengthen, and condition hair and nails, restoring moisture, elasticity, and shine.
