Hair loss and head and neck radiotherapy
This page tells you about how radiotherapy to the head and neck area may affect your hair. There is information about
Radiotherapy to the head always causes some hair loss. If you are having treatment to a particular part of your head or neck, your hair will only fall out in that area. But you may also have some hair loss on the opposite side of the head or neck, where the radiotherapy beams pass through. This is called the exit site. You may want to cut your hair short before the treatment starts as this may make the change less noticeable and easier to cope with.
When your treatment has finished, your hair will usually grow back. 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.
Men may have a permanent loss of beard growth depending on the position of the radiotherapy beams and the dose used.
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 or baby 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.
You may like to cover your head with a soft hat or scarf to protect the exposed skin and keep your head warm.
