Sunny Isle Original Jamaican Black Castor Oil in the 8 fl oz (236 ml) size.

Sunny Isle Original Jamaican Black Castor Oil is a traditionally processed hair and scalp oil designed to strengthen follicles, reduce breakage, and support longer, thicker hair over time. Made from organically grown Jamaican castor seeds that are roasted, ground by hand, and boiled to extract a pure, dark brown oil, each bottle carries a notably high ash content — the marker that distinguishes authentic JBCO from ordinary castor oil and makes it more effective at nourishing the scalp. The medium consistency absorbs well without leaving heavy residue, making it practical for weekly scalp massages or as an overnight treatment on dry ends. Applied regularly to eyebrows and lashes, many users notice improved fullness within a few weeks. The 236 ml bottle provides several months of consistent use when applied in targeted amounts, keeping the cost per use low. Free from added salt and harsh chemicals, it is also gentle enough to use on dry or sensitive skin areas. Sunny Isle holds GMP certification, so the formulation and potency are consistent from bottle to bottle. Pair with a wide-tooth comb and a moisturising leave-in conditioner for a complete wash-day routine.
