What is Jamaican Blac Castor Oil?
Jamaican Black Castor Oil is produced by roasting castor beans before extracting the oil. This roasting process creates the dark color, thicker consistency, and smoky scent that separate it from regular castor oil. The ash content from roasted beans is believed to improve scalp penetration and moisture sealing.
