Our castor hair oil contains castor seed oil and olive oil. It can nourish and protect hair, improve the health of hair follicles, promote hair growth, make hair soft and shiny, and protect the scalp and hair. Its usage is simple: take an appropriate amount of essential oil, apply it evenly to the hair, gently massage, wear a plastic cap or tie the hair, let the essential oil work for at least 20 to 60 minutes, and finally rinse it off with warm water. It can deeply awaken dormant hair follicles, promote the growth of new hair, and make hair healthier and denser.
