Strengthen, smooth, shine. The K18 Molecular Repair Hair Oil is a silicone-free, weightless serum powered by patented K18PEPTIDE™, plant-based oils (avocado, sunflower), and squalane. It works on two levels—penetrating to repair frizz-causing damage at the molecular core and smoothing the hair surface to reduce flyaways and boost shine. Clinically proven to control frizz for up to 24 hrs, increase shine by 104%, reduce split ends by 78%, and protect against heat up to 450 °F (232 °C)
