For hair growth

Cystine is an amino acid that is formed from two molecules of cysteine and contains sulfur. In cosmetics, it plays an important role in strengthening the structure of the skin, nails, and hair. Cystine promotes the formation of keratin, the main protein that makes up hair and nails, so it is actively added to products for hair growth, strengthening, and restoration. It also has antioxidant properties, protects cells from oxidative stress, stimulates skin regeneration, and maintains its tone. It is used in serums, ampoules, creams, and hair care products.
