All Skin Types, Including Sensitive.

K18 Leave-In Molecular Repair Hair Mask is a leave-in treatment built around K18Peptide (sh-Oligopeptide-78), a bioactive peptide developed to work at the molecular level to help rebuild the hair's internal disulfide bonds after damage from bleach, color, heat styling, and chemical services. The 50 ml bottle delivers roughly 25 applications and works in just 4 minutes with no rinse required.
Key Ingredients
  • K18Peptide (sh-Oligopeptide-78), a patented biomimetic peptide formulated to reconnect broken keratin chains in the hair's cortex
  • Hydrolyzed Wheat Protein and Hydrolyzed Wheat Starch to support strand strength and manageability
  • Behentrimonium Chloride, a conditioning agent that helps detangle and reduce breakage
  • Tocopherol (vitamin E) for antioxidant support
  • A rinse-free formula that sits on strands for 4 minutes before styling
Key Benefits
  • Deep hydration
  • Protects from environmental damage
  • Repairs and strengthens skin barrier
How To Use

Formulated for chemically treated, bleached, color-damaged, or heat-styled hair that needs strength and elasticity restored without weighing strands down. Best used for the first 4-6 washes following a color or lightening service, then every 3-4 washes to help maintain results.
