Castor Oil

Few natural oils have stayed as consistently popular as castor oil, and for good reason. Pressed from the seeds of Ricinus communis, it’s unusually thick and rich in ricinoleic acid, a fatty acid that makes up around 90% of its composition. That concentration sets it apart from most plant oils.

Ricinoleic acid binds to EP3 prostanoid receptors in the skin, which may explain its anti-inflammatory and moisturising effects. The oil creates a semi-occlusive barrier on the skin’s surface, slowing water loss without fully blocking airflow. Applied to hair and scalp, it coats the hair shaft, which may reduce breakage and improve shine over time.

Traditionally used across Ayurvedic medicine, ancient Egypt, and traditional African practices for skin, hair, and joint care, castor oil has a long history as a topical remedy. Research into ricinoleic acid suggests it may support wound healing and reduce localised inflammation. Some studies have explored its use for scalp conditions, though evidence remains preliminary and results vary between individuals.

People dealing with dry skin, brittle nails, or thinning eyebrows commonly reach for it. It’s also a staple for those experimenting with natural hair growth routines and anyone looking to cut back on synthetic skincare ingredients.
