Castor Bean (Ricinis Communis) Oil: Full of powerful omega 6 and 9 oils, and very high in ricinoleic acid, castor bean oil is a real beautician’s secret. Its ability to penetrate the skin makes it a perfect moisturizer while its nourishing oils are especially beneficial for the hair and scalp. Castor oil has been used to treat dandruff and other scalp and skin conditions for hundreds of years. Its high concentration of omega-6 and omega-9 oils help to strengthen and thicken existing hair follicles while encouraging the growth of new hair. Your grandmother kept a bottle in her medicine cabinet for a reason! You can find Castor Bean oil in our Styling Wax and Rugby Balm muscle rub.
