This potent oil is effective for treating dry, damaged hair, regrowing and strengthening hair, and is a proven natural treatment for acne. It also works well for lengthening and thickening eyebrows and eyelashes, making it an all-around, good natural product to incorporate into your daily beauty routine. Our Extra Dark JBCO formula has a thicker, richer consistency than the Original JBCO and the highest ash content, ideal for regrowing damaged, dry or fading hair. Sunny Isle's organic castor seeds are roasted and ground by a manual grinder and then the crushed beans are boiled to extract the 100% pure, dark brown, organic oil.  With a variety of uses for Jamaican Black Castor Oil, it's a must-have skin and body oil.
