K18 makes the impossible possible.
K18PEPTIDE™ is a biotech-developed peptide that mimics hair’s structure to reverse damage by reconnecting polypeptide chains and disulfide bonds broken during damage from bleach + color, chemical services, and heat*

Biomimetics is a fancy way of saying “learning from and mimicking nature.” By mimicking the natural structure and molecular makeup of keratin proteins, the K18PEPTIDE™ is the perfect puzzle piece to connect broken keratin chains to renew strength + elasticity.
K18 molecular repair, PEPTIDE PREP™ detox shampoo, and DAMAGE SHIELD shampoo + conditioner are formulated with the K18PEPTIDE™. In our molecular repair products, the peptide works at the innermost layers to reverse hair damage. In our PEPTIDE PREP™ detox shampoo, and DAMAGE SHIELD shampoo + conditioner, the peptide helps reduce protein loss to help keep hair feeling healthy and strong.
