Check if it's dandruff
Dandruff is a common skin condition. It's not harmful and you cannot catch it.
The flakes are often more noticeable in darker hair and if they fall from your scalp on to your shoulders.
Your scalp may also feel dry and itchy.
How to treat dandruff yourself
Use an anti-dandruff shampoo. There are several different types you can buy from pharmacies or supermarkets.
Look for shampoo containing one of these ingredients:
- zinc pyrithione
- salicylic acid
- selenium sulphide (or selenium sulfide)
- coal tar
Your pharmacist can tell you how to use the shampoo.
Use the shampoo for a month to see if your dandruff improves. You might need to try more than one type to find one that works for you.
Non-urgent advice: See a GP if:
- you still have symptoms after using anti-dandruff shampoo for a month
- your dandruff is bad or your scalp is very itchy
- your scalp is red or swollen
The GP can check your scalp for skin conditions that could be causing your dandruff.
Causes of dandruff
Dandruff is not caused by poor hygiene, although it may be more obvious if you do not wash your hair regularly.
Stress and cold weather may also make dandruff worse.
