Review on Natural Riches Organic Castor Oil: USDA Certified Cold Pressed Oil for Dry Skin, Hair Loss, Dandruff, and Thicker Hair Growth - Moisturizes and Heals Scalp, Skin, Hair. Enhances Eyelashes & Eyebrows -16 fl. oz. by Kristina Perez

Great product. I have very dry scalp and I use these 2 ways. I sometimes use it as a scalp treatment with hot oil and wash it off with my conditioner after 20 minutes under the plastic cap blow dryer. Or I apply it to my scalp in the evening before I wash my hair. I tie a scarf around my head so the pillow doesn't get dirty. I find that this method allows the product to penetrate deep into my scalp before washing and my hair will not be greasy after washing. As a result, the scalp is moisturized and the hair does not become greasy. I bought an empty tipped bottle from a cosmetics store and poured the product in to easily apply castor oil to my scalp. Works wonders!
