This leave-in treatment mask does cleanup duty after damage caused during bleaching, chemical services, and heat.

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.
