Much like skincare oils, hair oils contain a wealth of naturally beneficial properties (vitamins, fatty acids, antioxidants) that help bring life and luster back into your locks. Hair oils can be used to help prevent damage from heat-styling, split ends, breakage, and even hair loss, and they can also be used to help maintain your scalp health, detangle, de-frizz, and boost your overall hair health. In short: If you haven't already incorporated a good hair oil into your routine, it's time to start doing so. Here are the five best, grouped by category.
