CB Smoothe Wild Jamaican Black Castor Oil is a botanical scalp and hair treatment oil featuring black castor oil as its hero ingredient, combined with biotin, niacin, rosemary, peppermint, and vitamin E. The formula targets scalp circulation and follicle health with a lightweight, non-greasy texture designed for daily use. Applied via dropper to the scalp, it claims to promote fuller-looking, faster-growing hair while conditioning the lengths. The brand emphasizes clean ingredients—free from parabens, sulfates, and mineral oil—appealing to those seeking natural haircare. Growth claims are largely anecdotal, backed by user reports rather than clinical studies. Suited for all hair types, though best for those seeking scalp hydration and circulation support rather than guaranteed regrowth. The $9.32 price point (4oz) offers solid value per ounce in the scalp-oil category.
