Hair loss and brain radiotherapy

Radiotherapy to the head always causes some hair loss. If you are having treatment to a particular part of your head, your hair will only fall out in that area. But you may also have some hair loss on the opposite side of the head, where the radiotherapy beams pass through. This area is called the exit site.

Your hair will usually grow back when your treatment has finished. But it may not be quite as thick as before and in some people can be patchy. The more radiotherapy you have had, the longer your hair will take to grow back. In some people it may grow back a different colour, or curly when it used to be straight. 

You may like to cover your head with a soft hat or scarf to protect the exposed skin and keep your head warm. 

The video below shows you the different types of hats and scarves you can wear when you have hair loss.

You can find the stretchy headwear shown in the video at Buffwear.

Other people prefer to wear a wig until their hair grows back. You can get a wig on the NHS or buy one privately. We have information about how to get a wig.

You may want to cut your hair short before the treatment starts as this makes the change less dramatic and easier to cope with.

There are books and booklets about coping with hair loss, some of which are free. You can find details on our brain tumour reading list.


Hair washing tips

During your treatment, you will need to wash your hair carefully so that you don't make the area sore. Use warm or cool water and non perfumed shampoo only.

It is best not to use a hair dryer but to gently dry your hair with a soft towel. Or you can let your hair dry naturally. If the skin gets sore let your radiographer know and they will advise you how to care for the skin.
