What are the main benefits of castor oil for nails and skin, and how does it work?

Castor oil from Ricinus communis is valued for its unique composition, primarily ricinoleic acid, which gives the oil its rich, cushioning feel. This fatty acid, along with vitamin E and other lipids, helps condition the hair shaft and soften rough textures. When applied to nails and cuticles, it can help reduce the feeling of dryness and make the skin feel softer for longer by forming a protective barrier that locks in moisture.

For skin, it is particularly useful for dry, rough areas such as elbows, heels, and hands. The oil helps reduce moisture loss, leaving the skin feeling smoother and more resilient. It is not a substitute for a balanced diet or medical treatment, but rather a cosmetic aid to improve the appearance and feel of dry skin and brittle-looking hair. Regular application to these targeted areas can help maintain softness and reduce the coarse appearance of dry skin.
