The K18 Molecular Repair Hair Oil is a lightweight, biotech-powered treatment oil that goes beyond surface shine. Powered by the K18Peptide™, it penetrates deep into the hair fiber to reverse damage, reduce frizz, boost shine, and protect against heat up to 450°F (232°C)—without weighing hair down. This silicone-free formula smooths the hair surface, strengthens from within, and delivers a soft, polished finish that lasts, even in humidity. Whether used on damp hair before styling or as a final touch on dry hair, it leaves hair looking visibly healthier, shinier, and more manageable. Perfect for all hair types, including color-treated, damaged, or textured hair.
