The K18PEPTIDE™ is a biotech-developed peptide that mimics hair’s structure to reverse damage by reconnecting broken polypeptide chains and disulfide bonds, mimicking the natural structure and functionality of keratin proteins -bringing biomimetics to the hair science lab.

In salon treatments and at home, this science-powered set delivers cleaner, healthier, and frizz-free hair.

Start with Detox Shampoo to clear product buildup, excess oil, and metals from hard water.

Follow with the leave-in molecular repair hair mask—powered by the K18PEPTIDE™ and clinically proven to reverse damage from bleach + color, chemical services, and heat in 4 minutes.
