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*

*Disclaimers

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.

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.

Nope. Instead of temporarily patching only disulfide bonds, K18’s biomimetic

Peptide mimics the molecular makeup of keratin to reconnect peptide bonds,

hydrogen bonds, AND disulfide bonds along the length AND width of the hair fiber.

This delivers true, holistic hair strength + elasticity for all hair types.

Yes, it is better to use the full K18 routine for optimal service and molecular repair results.

To achieve the best cumulative results, we recommend using these routines:

when you need to repair damage: detox shampoo + mask

when you need to protect against daily damage: DAMAGE SHIELD shampoo + conditioner

every day: molecular repair hair oil

between wash days: AirWash™ dry shampoo

Before K18 molecular repair mask or oil, our PEPTIDE PREP™ detox shampoo tackles buildup + metals to create the cleanest, healthiest hair canvas. With our molecular repair formulas, you get maximum damage repair plus additional styling benefits with the oil. Use the DAMAGE SHIELD shampoo + conditioner to protect hair from daily damage between K18 mask days—and keep healthy hair going in-between salon appointments. Use AirWash™ dry shampoo to refresh hair between washes with an instant, weightless clean.

K18 is not organic as we employ both natural and synthetic ingredients to create the safest, most effective product to get our peptide where it needs to go. Our intentional innovations are all vegan and cruelty-free and prioritize radically simple, safe, and optimized hair health.
