Sunny Isle Jamaican Black Castor Oil (118.2 ml / 4 fl oz) is a pure, traditionally processed Jamaican black castor oil made from roasted castor beans. It’s commonly used to deeply nourish and moisturize hair and scalp, help strengthen strands, and support healthier‑looking hair growth, and can also be applied (sparingly) to skin, eyebrows, or lashes for added conditioning.
