Hair loss (alopecia)

Hair grows almost everywhere on the human body and is thickest on the head. Each hair is anchored into the skin by a hair follicle which holds the hair root. When the hair falls out, a new hair grows from the same hair follicle. It is normal to lose 50 to 100 hairs each day.

Damage to a hair follicle can cause its hair to fall out and prevent the follicle from growing new hairs. If many hair follicles are damaged, the hair becomes thinner and bald patches may appear. This is called hair loss or alopecia. Sometimes damaged hair follicles can recover and the hair will then grow back.

During cancer treatment, you may have experienced hair loss. Cancer treatment can damage the hair follicles, causing hairs all over the body to fall out within a few days or weeks. Usually this is only temporary and the hair grows back after the end of treatment. The hair might have a different colour, texture or style (curlier or straighter). It might also grow more slowly or become thinner. In some instances the hair follicles are too damaged and cannot recover. This is called permanent hair loss.

Am I at higher risk of (permanent) hair loss?

Anyone, including people who have never had cancer treatment, may develop (permanent) hair loss. However, there are some cancer treatments that may increase the risk of having (permanent) hair loss. The problems that can occur depend on the type of cancer treatment received.

The following treatments can increase the risk of (permanent) hair loss:

  • Radiotherapy can cause hair loss in the area that was treated. Hair loss after radiotherapy can be temporary or permanent. This depends on the dose and the number of treatments.
  • Chemotherapy can cause temporary hair loss all over the body. Chemotherapy alone usually does not cause permanent hair loss.
  • Stem cell transplantation can cause temporary hair loss as this involves high doses of chemotherapy.
  • Treatment with both radiotherapy and chemotherapy can increase the risk of having permanent hair loss.

You can find out if you have received any of these treatments by looking at your treatment summary. If you do not have a treatment summary or if you have any questions, do contact your treating hospital.

If you experience hair loss, it does not always mean that this is caused by your cancer treatment. Hair loss may have other causes.

What happens if I have (permanent) hair loss?

Hair loss can be very upsetting, especially when the hair loss is permanent. Sadly, there are no lotions or treatments which will help the hair to grow back. But there are several things which can help to make thin hair or bald areas less noticeable.

You can try different hairstyles, hats, scarves, bands, hair pieces or wigs. Another good (but expensive) option is hair weaving, where extra natural or artificial hair is added to the places where the hair is thin. A hairdresser can help if you want to try any of these options.

Hair transplants are generally not recommended when you received radiotherapy. Skin treated with radiotherapy is often thin and does not heal well, which makes transplanting new hair difficult. If you would still like to try having hair transplant, discuss this with your general practitioner or follow-up care specialist.

What else can I do?

Experiencing (permanent) hair loss can be difficult. Talking to friends and family can be helpful as well as specialist counselling and/or contact with support groups, such as patient organisations. For more information on taking care of your mental health, please read: Mental health problems.

Although it may not influence your (permanent) hair loss, it is still important to live a healthy lifestyle. Taking care of your mental health may be beneficial; even small changes to your lifestyle can have a positive impact on both your physical and mental health. For more information on taking up a healthier lifestyle, please read: Health promotion.

If you have any further questions or if the information in this brochure concerns you, please contact your general practitioner or follow-up care specialist.
