K18 Leave-In Molecular Repair Hair Mask 50ML

K18PEPTIDE™ is a biotech-engineered peptide designed to mimic the natural structure of hair. It reverses damage by reconnecting broken polypeptide chains and disulfide bonds caused by bleaching, coloring, chemical treatments, and heat styling.

Formulated with a pH of 5.0–6.0, it helps reduce cuticle swelling and optimizes protein conditions to restore hair to its most resilient state.

The lightweight cream format ensures easy, even application across all hair types, delivering detangling and softening benefits.

Vegan, color-safe, and cruelty-free.

K18 goes beyond traditional repair by reconnecting both polypeptide chains and disulfide bonds, restoring strength along the full length and width of the hair for deep, lasting repair.

It targets even the most extreme damage by penetrating the innermost layers of the hair, rebuilding core strength and elasticity for hair that feels smooth, strong, and naturally bouncy.

Results are both immediate and long-lasting — hair begins to repair from the first use and continues to improve, even after washing.

The leave-in formula simplifies your routine: just apply and let it work in 4 minutes—no rinsing required.

Because K18PEPTIDE™ acts at the molecular level—where all hair is the same—it’s effective on all hair types.
