There is no proof that oiling the scalp gets rid of dandruff. Oil on the scalp can feed the yeast linked to dandruff and make seborrheic dermatitis worse, and using oil instead of anti-dandruff shampoo can delay proper care.

What experts say

Dandruff can be caused by a yeast that lives on skin and by skin conditions such as seborrheic dermatitis and eczema.2
Hair oils can feed that yeast and may make seborrheic dermatitis worse when put on the scalp.1
Anti-dandruff shampoo is the usual treatment; it can take up to 4 weeks, and you may need to try more than one type.2
Dandruff is not caused by poor hygiene, though it may be more noticeable if you do not wash your hair regularly.2

Why people believe it

People often think dandruff means a dry scalp, so oil feels like it should soothe it. Oils are also a traditional hair care habit and can make hair look smoother.

What to do

If you have dandruff, use an anti-dandruff shampoo. Give it up to 4 weeks.2
If one type does not work, you can try another type.2
If a doctor has said your dandruff is from seborrheic dermatitis, keep oil off the scalp; you can put oil on the ends of your hair instead.1
Ask a pharmacist how to use the anti-dandruff shampoo.2

See a doctor if

Dandruff is still there after using anti-dandruff shampoo for at least 4 weeks.2
Dandruff is bad or the scalp is very itchy.2
The scalp is red or swollen.2
There are flaky, itchy patches on the face or other parts of the body.2
