Castor oil increases hair growth, treats dandruff and repairs split ends. Castor oil also acts as a moisturizer for both the hair and the scalp.
Individuals with thinning hair can effectively re-grow hair by simply massaging castor oil into the hair and scalp, allowing it to sit overnight, and then washing it away the next morning. Anti-fungal properties found in castor oil combat infections on the scalp, while natural moisturizing properties treat dry skin, curing dandruff. Castor oil also repairs split ends.
Castor oil is a relatively thick oil, making it difficult to wash out. To thin the castor oil, mix coconut oil or jojoba oil in equal amounts with the castor oil. This mixture has the same effects on the hair as straight castor oil.
