Instead of creating another haircare product that temporarily repaired hair damage or, worse, simply coated it to make it feel like it had been repaired, K18 founders took a radical biotech approach and is on a crusade to liberate haircare. The patented, clinically proven K18Peptide™ restores hair by reversing the damage done by chemical treatments, bleach, color, and heat. As a leave-in formula, the tiny peptide molecules connect the broken polypeptide chains, making hair look and feel soft, healthy, and lustrous.
