Coconut oil, often used in combination with sugar or salt, is a natural emollient that can help nourish the scalp and hair. Rich in fatty acids, coconut oil penetrates deeply into the hair shaft, providing hydration and improving overall hair health. When used in a scrub, coconut oil not only moisturizes the scalp but also acts as a copyright oil for other essential oils, ensuring that the beneficial properties of the oils are absorbed effectively.
