K18 Leave-In Molecular Repair Hair Mask

The K18 Leave-In Molecular Repair Hair Mask is a revolutionary treatment designed to reverse hair damage caused by bleach, color treatments, chemical services, and heat styling. Utilizing the patented K18PEPTIDE™, this mask works at the molecular level to reconnect broken keratin chains, restoring hair's strength, softness, smoothness, and bounce. Clinically proven to repair damage in just 4 minutes, it offers immediate and lasting results, making it suitable for all hair types.

After shampooing, skip the conditioner. Towel-dry hair thoroughly, then apply 1-3 pumps of the K18 mask, depending on hair length and density. Work evenly into hair from ends to roots, one pump at a time. Let the product sit for 4 minutes to activate. Do not rinse out. After the 4-minute activation period, style as usual. For best results, use consecutively for 4-6 washes, then as needed for maintenance.

The key active ingredient is the K18PEPTIDE™ (sh-Oligopeptide-78), a biotech-developed peptide that mimics the natural structure of keratin to repair and strengthen hair from the inside out. Additional components like Hydrolyzed Wheat Protein and Hydrolyzed Wheat Starch provide further conditioning and protective benefits.
