Castor oil is known to promote hair growth by stimulating blood circulation to the scalp. Coconut oil, olive oil, baobab oil, and jojoba oil are rich in essential fatty acids that deeply moisturize and nourish hair, making it more supple and less prone to breakage. They also have restorative properties that can help seal split ends and prevent further damage. Sunflower and vitamin E oils are rich in antioxidants that protect hair from damage caused by free radicals, UV rays, and other environmental aggressors.
