Weekly applications of black castor oil can reverse damage done to skin and hair over the years. Use castor oil to nourish your scalp and strengthen the roots of your hair. The essential nutrients in castor oil increase blood circulation to the scalp, hence accelerate positive and healthy conditions for your skin and hair.
To use it weekly as a hot oil treatment, start with clean hair and scalp. Then, just massage the castor oil into scalp and hair, then cover with plastic cap and go under the dryer for 15-30 minutes. Be sure to apply the castor oil to the scalp and not only on the tips of the hair. This will help make sure the maximum amount is absorbed and so that it can help nourish the hair follicles. You could even leave the oil on the scalp overnight.
