What is hair oiling?

Hair oiling is the practice of applying oil to the scalp and hair, often with gentle massage, and leaving it on before washing. It is a long-standing tradition in India, where regular oiling has been passed down through families for generations.

What research shows

Coconut oil can penetrate the hair shaft and reduce protein loss from both damaged and undamaged hair when used before or after washing; mineral oil and sunflower oil did not show the same effect in the same study. (Rele & Mohile, 2003)

Oils also coat the hair, reducing friction and the swelling that can stress the fibre during washing. Scalp massage itself has been studied for hair thickness, with small, early findings. (Koyama et al., 2016)

Limits and practical notes

Oiling conditions and protects the hair fibre, but evidence that it makes hair grow faster is limited. Heavy or very frequent scalp oiling may not suit oily or dandruff-prone scalps. Wash out thoroughly, and patch-test new oils.
