Why people oil their scalps
It's a long-standing practice in many hair-care traditions, often as part of a pre-wash ritual. People commonly report comfort, reduced tightness and easier detangling afterwards.
What the evidence supports
Cosmetic effects on the fibre — lubrication, reduced friction, in some cases reduced protein loss during washing — have reasonable support.
The claim that applying oil to the scalp increases the rate at which follicles produce hair does not have that support. Treat it as unestablished.
Reasonable cautions
- Heavy oils left on for long periods can contribute to buildup for some people.
- If your scalp is already flaky, itchy or inflamed, oiling can make things worse rather than better.
- Dilute essential oils; they are potent and can irritate.
- Stop anything that stings, burns or produces a rash.
