Castor Oil
Castor oil is one of those single-ingredient classics that keeps finding new fans. Pressed from the seeds of the castor plant, it's a thick, rich oil that has become a fixture in hair, brow, lash and skin routines. This aisle carries it pure — including organic, hexane-free bottles from Naka Platinum and NOW Solutions in sizes from small starter bottles up to litre formats — plus castor oil lotions for an easier, less-messy way to use it every day.

The two label details shoppers check first are "cold-pressed" and "hexane-free." Cold pressing means the oil was extracted without heat, and hexane-free confirms no chemical solvents were used — both signs of a minimally processed oil. Several bottles here also carry the manufacturer's organic certification. Castor oil is noticeably thicker than oils like jojoba or sweet almond, and that's part of its appeal: a little goes a long way, and many people thin it with a lighter carrier oil for easier spreading.
Most shoppers use castor oil cosmetically — massaged into the scalp and hair ends, brushed onto brows, or smoothed over dry patches of skin. Castor oil packs, where the oil is applied to a cloth and rested on the skin, remain a popular traditional practice as well. If the thick texture or the ritual isn't for you, the castor oil lotions blend it into an everyday moisturizer format you can apply straight from the tube. Whichever you choose, store it away from heat and light.
