Keratin is a highly specialized fibrous protein naturally found in hair, feathers, wool, and nails. It plays an important role in strengthening and protecting hair and skin structures. Unlike many other proteins, keratin is rich in cysteine, an amino acid that contributes to its strong structural properties.

Keratin protein hydrolysate is commonly used in hair care and cosmetic formulations due to its ability to improve hair strength, enhance texture, and provide nourishment. The product is processed with strict quality control to maintain purity, stability, and consistent performance for cosmetic applications.
