Sunny Isle Jamaican Black Castor Oil is processed the “old fashioned “Jamaican way. The Organic seeds are roasted and ground by a manual grinder, after which the beans are boiled to extract the 100% pure, dark brown organic oil. Compared to other brands, it is the darkest Jamaican Black Castor Oil because Sunny Isle roast their beans longer, which produces more ash content than in other brands on the market. Sunny Isle believes that their higher ash content increases the effectiveness of their oil. Sunny Isle also offers other organic oils for healthy hair and skin.
