Cancer treatment and hair loss
Some cancer treatments can cause hair loss or hair thinning, which is called alopecia. Cancer treatments can also slow hair growth. Any treatment that acts on rapidly dividing cancer cells can also affect other rapidly dividing cells such as hair follicles.
Whether you lose your hair or not can depend on the type of drug or drug combination you’re having; the dose; your reaction to the drug or drugs used; or your drug treatment in the past.
Hair loss can happen anywhere on the body, including the scalp, eyebrows, eyelashes, chest, underarms, face (beard and moustache) and pubic area.
Before treatment starts, talk to your doctor about whether you are likely to lose your hair, and if so, the level of hair loss to expect.
Chemotherapy and hair loss
Chemotherapy (also called chemo) is the use of drugs to kill or slow the growth of cancer cells. Depending on what type of chemotherapy you receive, you may experience complete hair loss, hair thinning or your hair may stay the same.
Chemotherapy drugs are usually given in cycles, and the amount of hair loss depends on the type of drug, the dose and the timing of treatment. If hair loss occurs, it usually starts during cycle two or three, although it can start after the first cycle.
Eyelashes and eyebrows may take longer to fall out. Hair loss can happen suddenly or gradually. Before and while your hair is falling out, your scalp may feel hot, itchy or tender.
You may find that the skin on your head is extra sensitive, and you could develop pimples on your scalp. Some people use scalp cooling to reduce hair loss from the head.
Using scalp cooling
Some treatment centres provide scalp cooling or cold caps. Scalp cooling can reduce hair loss from the head by lowering the temperature of your scalp.
This reduces blood flow in the scalp, which can lessen the amount of chemotherapy that reaches the hair follicles on your scalp.
Scalp cooling doesn’t always stop hair loss, and can only be used by people having intravenous chemotherapy (through a drip). It works better with some chemotherapy drugs than others.
Scalp cooling is not an option for people being treated for blood cancers or having radiation therapy to the scalp. Scalp cooling involves wearing a cap connected to a cooling unit.
You wear it before, during and for a while after the chemotherapy session. Some people find it uncomfortable or painful, so your doctor may suggest taking pain medicine beforehand.
You may also feel cold so bring warm clothes. If you’re interested in scalp cooling, ask your treatment centre if it’s an option for you.
Radiation therapy and hair loss
Radiation therapy (also called radiotherapy) uses controlled radiation doses to kill cancer cells or damage them so they do not grow, multiply or spread.
If you have hair in the area being treated, you may lose some or all of it during or just after radiation therapy. Hair will only fall out in the area of the body being treated.
For example, if you are having radiation therapy to your head, you may lose some hair from your scalp; if your chest is being treated, you may lose hair from that part of your body.
Hair regrowth or thickening may start within a few weeks or months after finishing treatment, but sometimes hair loss is permanent.
“I thought I would keep my eyelashes and eyebrows. They fell out weeks after my hair – it was a shock all over again.” Nina
How you might feel
If you lose your hair, you may experience a range of different emotions including anger, anxiety and sadness.
For some people, hair is an important part of their identity, and losing the hair on their head or face (beard, moustache, brows and lashes) can be distressing.
Other people may find the experience is not as bad as expected. Everyone is different – there is no right or wrong way to respond.
Some family members and friends may not know how to react to your hair loss. If you are uncomfortable talking about it, give a simple response (e.g. “I’m having some treatment for my health and this is one of the side effects.”).
Children may get upset or feel anxious about hair loss. See Talking to Kids About Cancer for tips on how to talk to children about the changes treatment for cancer may cause, including hair loss.
“We found humour was very helpful. We joked that our daughter could paint my head. I also encouraged her to touch my head and feel how strange it felt. We discussed how my hair would come back.” Melanie
Ways to take back some control
Being prepared, talking about how you feel and planning ahead for the possibility of treatmentrelated hair loss may be helpful.
- Cutting your hair before treatment can give you time to adjust. You might choose to cut your hair short straightaway, or cut it in stages.
- Some people choose to shave their head (and beard) in the early stages of hair loss when they start to notice larger amounts of hair falling out.
If you are upset about hair loss, you can talk to someone about how you feel, such as your GP, specialist, nurse or psychologist. You can also call Cancer Council 13 11 20.
Taking care of your hair and scalp
If you have lost your hair:
- when outdoors, protect your scalp from the sun with SPF50 or SPF50+ broad-spectrum, water-resistant sunscreen and a hat
- moisturise your scalp using a non-perfumed lotion to help reduce flaky and dry areas
- use a pillowcase made from a smooth fabric such as cotton sateen or bamboo
- consider wearing a soft cap, beanie or turban to keep your head warm.
If your scalp is sensitive and your hair is thin:
- use a gentle shampoo and conditioner
- brush your hair gently with a soft-bristle brush
- dry your hair naturally or use a cool setting on the hairdryer
- avoid using heated rollers, curling wands or straighteners
- avoid having your hair coloured, chemically straightened or permed.
If you have any concerns, discuss them with your cancer care team or call Cancer Council 13 11 20 for more information.

Wigs, turbans, scarves and beanies
Some people choose to wear head coverings such as a wig, hat, scarf, turban or beanie after losing their hair.
If wearing a scarf, choose one that is at least 50 cm long so it covers the scalp. Cotton, lightweight wools or blends are the best fabrics to use, as nylon or silk tend to slip off the head too easily.
A broad-brimmed hat offers more sun protection for outdoors.

Types of wigs and hairpieces
Wigs and hairpieces can be made of different materials, including:
- Human hair – usually more expensive. It can be styled like normal hair with hot rollers, curling wands and straighteners, trimmed and coloured darker but not lighter. It is heavier and will last longer.
- Synthetic hair – is less expensive, lighter, dries quickly and needs less care. Synthetic hair can’t be restyled or recoloured. If you look after a synthetic wig, it can last for as long as a human hair wig.
Selecting a wig
If you want to match a wig to your usual colour and style, it’s a good idea to start looking before treatment or hair loss begins. You can also use a photo from before hair loss began.
Some people like to try a new look and choose a different style and colour. Here are some tips for selecting a wig:
- Take a friend or family member along with you for support and to help you choose your wig.
- Ask your hairdresser or speak to a consultant at a wig salon about a style of wig that would suit you. There may be a cost involved for a wig consultation. Remember to ask about the cost when making an appointment or before making your decision.
- Look for a wig that adjusts to any head size to allow for variations as you lose your hair. Some people choose a wig after hair loss as this can often provide a better fit.
- Visit specialty wig suppliers who are experienced in fitting wigs for people having cancer treatment. Call Cancer Council 13 11 20 or search the internet for suppliers.
Paying for a wig or hairpiece
You may be able to get help with the cost of your wig or hairpiece.
- State and territory governments – you may be eligible for financial help towards the purchase of a wig. Ask your nurse or social worker for information or call Cancer Council 13 11 20.
- Private health insurance – some policies will cover part of the cost of a wig if you lose your hair due to disease or treatment. Before you buy your wig, check what your fund will pay and what information you may need to provide (e.g. letter from a health professional).
- Department of Veterans’ Affairs – veterans may be eligible to have the cost of a wig covered.

After treatment
Hair loss caused by treatment for cancer is usually temporary. Talk to your doctor about what to expect after your treatment.
- After chemotherapy – The first soft hairs usually start to reappear 4–6 weeks after treatment ends. Hair usually grows about 1 cm every 4 weeks so after 4–12 months, you may have a reasonable amount of hair.
- After radiation therapy – The time it takes and the way hair grows back depends on the dose of radiation you receive. Hair usually grows back a few months after treatment. Occasionally, after a large dose of radiation therapy, the hair may not recover completely, new growth may be patchy and there may be some permanent hair loss.
- After other drug therapies – Hair thinning or slowed growth caused by hormone therapy will usually improve, but it can take a few months. If you experience hair thinning after immunotherapy or targeted therapy, hair usually starts to grow back when treatment has finished.
As your hair grows back, it may be curlier, thicker or finer than it was before treatment, or it may be a different colour. Often these changes are not permanent.
A hairdresser may be able to help you manage thinning hair and hair care during regrowth. Talk to your hairdresser about different styling to give the appearance of thicker hair. Hairpieces can be effective in covering partial hair loss.
Ask your doctor or nurse about how soon after treatment you can colour your hair – for example, it is often recommended that people wait at least six months to colour their hair after chemotherapy has finished.
If your scalp is sensitive, your hairdresser may be able to suggest dyes that may be gentler on the hair and scalp than chemical hair treatments.
