## Description

(Pet Plastic Bottle 8oz)When you're searching for a powerful and versatile hair and skin care product, look no further than Sunny Isle Extra Dark Jamaican Black Castor Oil. This potent oil is effective on dry, damaged hair. It also works well for boosting the appearance of eyebrows and eyelashes, making it an all-around, great 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 nourishing the scalp and treating 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.

Review: Sunny Isle Castor oil - This is a good product to use. It moisturizes and helps with hair growth once used consistently.
Review: Consistent Quality, Clearly Natural and Thicker Than Cheaper Options - 1- Currently using this extra dark castor oil overnight every 3-4 days with Peppermint Oil from about 1.5 months to get thicker hair; I might mix in flaxseed oil to the whole mix to make the hair mask slightly thicker. 2- The quality of the oil has been consistent and is natural to the point where it had, what looked to be, natural roots within the bottle. My 2 Cents: Given the thicker consistency of the product compared to cheaper castor oil it, at least seems to me, to be more nutritious for the hair. It's worth trying if you don't mind the higher price difference compared to ordinary castor oil.
