K18 Biomimetic Hairscience - Leave-In Molecular Repair Hair Mask

K18's molecular repair leave-in hair mask penetrates deeper into the hair than traditional repair products. The revolutionary patented peptide, K18Peptide™, is just the right size to fit in and reconnect broken keratin chains, renewing hair with strength, softness, and elasticity. You will feel the difference from the very first use.

K18Peptide™ is the future of hair care in a single patented peptide:

Any chemical process involving an alkaline environment breaks the keratin chains that keep hair together and strong. K18 is the first product in history to reconnect broken keratin chains. It does this by penetrating the cortex and rebuilding disulfide bonds on both sides of the ladder, reconnecting the broken keratin chains. Hair is repaired, regaining strength and elasticity as if it had suffered virtually no damage at all.

• K18Peptide™ is clinically proven to reverse damage in just 4 minutes.
• Heals damage caused by bleaching, coloring, chemical services, and heat.

How to use:
