K18 Leave-In Molecular Repair Hair Mask


An at-home leave-in treatment infused with our patented K18Peptide™ that works to repair even the most extreme damage, renewing hair to its most youthful, healthy state.

Traveling deeper into the inner layers of hair than traditional repair products, revolutionary patented K18Peptide™ reconnects broken keratin chains, renewing hair with strength, softness, smoothness, and bounce. You can feel and see the difference with the first use.

For best results, use for the first 4-6 consecutive washes, then every 3-4 washes as needed to maintain hair strength.
