K18 Professional Molecular Repair Hair Mask 5 oz

Professional, at-home hair treatment mask with a patented peptide. K18 Leave-In Molecular Repair Hair Mask 5 oz repairs and restores your keratin levels while strengthening the cuticle of each strand from root to tip for more youthful vibrancy! A cupboard full of products can't give you the results that K18's new leave in treatment does! When it comes to damage control, this is all you need. This easy-to-use formula penetrates deep into your strands for repair on every level. The microscopic level where Keratin meets Keratin is restored by K18Peptide so less breakage occurs. Alongside repairing damaged proteins, there's a conditioning ingredient that strengthens any weakened or brittle areas.
