Hair loss during chemotherapy: what to ask your cancer team
The likelihood of loss, scalp-cooling options and regrowth depend on the cancer treatment and your circumstances.
On this page
Some chemotherapy treatments cause hair loss, but the extent varies with the medicines and regimen. Your cancer team can explain what is likely with your treatment and whether scalp cooling is an option. Do not delay or alter cancer treatment to follow general hair-growth advice.
Why chemotherapy can affect hair
Some chemotherapy medicines affect rapidly dividing cells, including cells involved in producing hair. Loss may involve the scalp, eyebrows, eyelashes or body hair, depending on treatment. Some people experience thinning; others lose more hair.
The timing and extent are not identical for everyone. Ask the team what to expect from your particular regimen and whether any other part of treatment may affect the hair or scalp. Macmillan's hair-loss information covers practical support and the different issues people may face.
Discuss scalp cooling before treatment starts
Scalp cooling may reduce chemotherapy-related hair loss for some people, but it is not suitable for everyone and cannot guarantee that hair will be retained. Its suitability depends on the cancer, medicines and clinical circumstances.
Ask whether it is available, what the sessions involve and how it would fit with your treatment. Macmillan's scalp-cooling guide explains the practical considerations and limitations. The oncology team should guide the decision.
Caring for hair and scalp
Use the advice given by your team for washing, styling and any sensitive skin. Gentle handling may help reduce avoidable discomfort or breakage, but it cannot guarantee prevention of drug-related hair loss. Avoid adding strong products to an irritated scalp without checking first.
Wigs, scarves, hats and other options can be discussed before you need them, if that feels helpful. Choosing to cut or shave the hair is personal; it is not medically necessary for everyone. Macmillan's cancer hair-care advice includes considerations for different hair types.
Regrowth after treatment
Hair often regrows after chemotherapy, but timing, texture and fullness can vary. Persistent hair loss can occur with some treatments. A fixed promise that hair will return within a particular number of weeks would be misleading.
If recovery is slower than expected, ask the cancer team whether assessment is needed. They can consider the treatment history and whether another cause contributes. Avoid starting supplements or hair-growth medicines without checking for interactions and suitability.
Where a hair transplant fits
Transplantation is not a routine solution during active chemotherapy. Persistent loss after treatment needs a diagnosis and assessment of scalp health, donor supply and overall medical suitability. The oncology team and any hair specialist should coordinate advice.
It would be inappropriate to promise that every remaining patch can be filled, or that surgery is possible whenever some donor hair remains. Our general transplant guide describes the operation, but an individual cancer-treatment history requires additional clinical consideration.
Questions and answers
Does every chemotherapy medicine cause complete hair loss?
No. The effects vary with the regimen and person. Ask your cancer team about the treatment you are receiving.
Does scalp cooling guarantee that I keep my hair?
No. It may reduce loss in suitable circumstances, but effectiveness varies and it is not appropriate for everyone.
Can I start minoxidil or supplements during treatment?
Check with the cancer team before starting a hair-growth product or supplement. General advice cannot account for your medicines and treatment plan.
