K18 Leave-In Molecular Repair Hair Mask 1.7 Oz

Formulated with a first of it's kind, patented oligopeptide, also known as K18Peptide™, this bioactive treatment reduces split ends, breakage and color fade, while restoring elasticity, bounce, softness and strength. Unlike conditioning treatments that hydrate the outer layer of hair and bonding treatments that wash out over time, this professional treatment actually heals hair from the inside out and produces results that won't wash away.
