Causes
Why is my scalp so oily?
Genetics and hormones
Some scalps simply produce more sebum, especially during puberty or periods.
Washing too little — or too harshly
Build-up traps oil; stripping shampoos can make the scalp overproduce.
Heavy products
Oils, serums and conditioner at the roots weigh hair down.
Touching your hair
Fingers spread oil from scalp to lengths.
Routine
How to get rid of an oily scalp
1. Wash as often as you need
Daily washing is fine with a gentle shampoo.
2. Clarify weekly
A salicylic acid or clarifying shampoo removes build-up.
3. Condition the ends only
Keep conditioner off the scalp.
4. Rinse with cool water
Hot water stimulates oil.
5. Use dry shampoo sparingly
It absorbs oil but builds up if overused.
Help
When to see a GP
See a GP if oiliness comes with red, itchy, flaky patches — it may be seborrhoeic dermatitis, which responds to medicated shampoos.
