Description
K18 Professional Molecular Repair Hair Mask 150ml is an innovative leave-in hair treatment designed to repair and restore damaged hair at the molecular level. Powered by patented K18Peptide™ technology, this professional-grade hair mask works to reverse damage caused by bleaching, coloring, chemical treatments, heat styling, and environmental stressors, helping hair regain its strength, softness, smoothness, and elasticity.
