Applying hydrolyzed protein to the hair may attract it with the hair through positive and negative charges, and it will be more firmly attached to the hair.
Hydrolyzed keratin peptides are derived from natural keratin such as chicken feathers or duck feathers, and are extracted using biological enzyme digestion technology.
