Extra dark castor oil is a thick, highly viscous, and deeply nourishing plant-based oil known for its signature dark amber to near-black color and distinct smoky, roasted aroma. Unlike clear, cold-pressed castor oils, it is crafted using a traditional Jamaican method where raw organic castor seeds are first roasted, manually crushed, and then boiled in water to extract the pure oil. Extra dark castor oil (most commonly found as Jamaican Black Castor Oil) features a higher ash content and a thicker, richer consistency than regular or original castor oil. It is highly prized for deeply nourishing dry scalps, promoting hair growth, sealing moisture in natural hair, and treating skin dryness.
