What Is Hydrolyzed Wheat Protein?

Hydrolyzed Wheat Protein is a plant-derived protein obtained by breaking down wheat gluten into smaller peptide fragments. These smaller molecules can penetrate the hair shaft to strengthen from within while larger fragments coat the surface for protection. It is one of the most popular vegan protein alternatives to animal-derived keratin.

Source: Wheat grain (Triticum vulgare) gluten

Origin: Natural

Also known as: Wheat Protein, Wheat Amino Acids, Hydrolyzed Wheat Gluten

What Does Hydrolyzed Wheat Protein Do to Your Hair?

Hydrolyzed Wheat Protein penetrates into the hair cortex to fill gaps in damaged protein structures, strengthening the hair from the inside out. Larger molecular weight fractions coat the exterior to smooth the cuticle and add shine. It also has moisture-binding properties that help maintain the protein-moisture balance essential for healthy hair.
