K18 Biomimetic HairScience Damage Shield Protective Conditioner is a nourishing and protective formula designed to shield hair from daily damage and maintain overall hair health. Engineered with K18’s patented K18Peptide™, this conditioner replenishes protein lost during washing, fortifies hair’s exterior lipid barriers, and enhances natural shine.
