Explore k18
Explore the power of K18 Hair best sellers; scientifically formulated to repair, strengthen, and transform all hair types. Featuring the award-winning K18 Leave-In Molecular Repair Hair Mask and the ultra-lightweight Molecular Repair Hair Oil, these top-rated treatments work on a molecular level to reverse damage caused by color, bleach, heat, and styling. Powered by K18’s patented K18PEPTIDE™ technology, each product delivers optimal effectiveness in fewer steps, with fewer ingredients, and in less time.

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* *www.k18hairpro.com/pages/disclaimers
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.
