K18 Pro - Leave-in Molecular Repair Hair Mask - 150ml

K18 Pro - Leave-in Molecular Repair Hair Mask - 150ml Powered by the K18PEPTIDE™ to reconnect broken polypeptide chains and disulfide bonds to renew strength and elasticity in just 4 minutes. 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. pH level of 5.0-6.0 helps close down the cuticle to seal in the K18PEPTIDE™ for lasting strength + elasticity. Powered by the patented K18PEPTIDE™, engineered over 10 years in a biotech lab to work on the molecular level to rebuild hair from the inside out in just 4 minutes.
