Dandruff

Dandruff causes white flakes of skin to appear on the scalp and in the hair.

The flakes are often more noticeable in darker hair and if they fall from your scalp onto your shoulders.

Your scalp may also feel dry and itchy.

Use an anti-dandruff shampoo to treat dandruff. There are several different types you can buy from pharmacies or supermarkets.

Look for a shampoo that contains 1, or more, of these ingredients:

• zinc pyrithione
• ketoconazole
• coal tar
• salicylic acid

A pharmacist can tell you how to use the shampoo.

Use the shampoo for up to 4 weeks to see if your dandruff gets better. You might need to try more than 1 type to find a shampoo that works for you.

Dandruff is not usually serious but if symptoms last a long time or become painful, you may need medical help.

• you still have dandruff symptoms after using anti-dandruff shampoo for at least 4 weeks
• your dandruff is bad or your scalp is very itchy
• your scalp is red or swollen
• you have flaky, itchy patches on your face or other parts of your body

The GP can check your scalp for skin conditions that could be causing your dandruff.

Dandruff is not caused by poor hygiene, although it may be more obvious if you do not wash your hair regularly.

It may be caused by different things, including a type of yeast that naturally lives on your skin, and skin conditions such as eczema.

Stress and cold weather may also make dandruff worse.
