K18 Molecular Hair Repair Mask is a 2-park in-salon treatment for all hair types that clinically reverses damage in 4 minutes. The patented peptide technology works to repair damage from bleach, color, chemical services & heat – restoring strength, softness, smoothness, and bounce.

The K18PEPTIDE™ works at the innermost layer of hair, reconnecting polypeptide chains and disulfide bonds broken during bleaching, chemical services, and through heat damage.

By addressing these damage sites at the innermost layer of hair, core strength and elasticity are renewed for strong, smooth, bouncy hair—even after the most extreme damage done in the salon or at home. This miracle in-salon treatment is vegan, color-safe, cruelty-free and is also available as an at-home mask for weekly professional maintenance as well.
