Kose Stephen Knoll Repair & Control Hair Oil W - Damaged Hair Treatment is formulated with a blend of key ingredients designed to restore and protect damaged hair. The product features argan oil, which is rich in antioxidants and vitamin E, providing deep hydration and nourishment to repair split ends and improve hair elasticity. It also includes macadamia nut oil, known for its high content of palmitoleic acid, which helps to strengthen hair follicles and reduce breakage by penetrating the hair shaft to restore moisture balance. Additionally, the formulation contains camellia oil, which offers a lightweight texture to smooth the hair cuticle, reduce frizz, and add shine without weighing hair down. These ingredients work synergistically to repair damage from heat styling and environmental stressors, control frizz, and enhance overall hair health, leaving hair feeling soft, manageable, and revitalized with regular use.
