This anti-dryness oil therapy can be used as often as needed to treat chronically dry hair, improve weak ends, and enhance growth. CARE TIP: Use this as the “oil” in your L.O.C. method (Leave-in, Oil, Cream). To use as a hot oil treatment, apply to clean hair, damp hair, cover with a plastic cap and sit under a warm, hooded dryer for 10 minutes, then rinse.
