Last updated October 2026 · This guide shares general information. Always follow the advice of your oncology team about your own treatment.
Hair loss from chemotherapy usually begins two to four weeks after treatment starts, and for most people hair begins to grow back within a few months after treatment ends. Not every treatment causes hair loss, so ask your care team what to expect. If hair loss is likely, choosing a wig or head covering before treatment begins can make the change feel more manageable and help you feel like yourself throughout treatment.
At a Glance
- Before treatment: ask your care team whether your treatment usually causes hair loss, consider a shorter haircut, and choose a wig while you have the most energy.
- Two to four weeks after starting chemotherapy: hair often begins to thin or fall out, sometimes over a week or two.
- During treatment: be gentle with your scalp, protect it from sun and cold, and wear soft, breathable caps and liners.
- After treatment: new growth usually starts within weeks to a few months, and may come back with a different texture or color at first.
Will I Lose My Hair?
It depends on your treatment. Some chemotherapy medicines cause complete hair loss, others cause thinning and some cause little or none; the type of medicine and the dose both matter. Radiation usually causes hair loss only in the area being treated. Your oncology team is the best source for what to expect from your specific plan.
When Does Hair Loss Start, and When Does It Grow Back?
According to the National Cancer Institute and Mayo Clinic, hair usually starts to fall out two to four weeks after chemotherapy begins. Your scalp may feel tender beforehand. Hair often begins to grow back within weeks to a few months after your last treatment, and many people see fuller regrowth in three to six months. New hair is often softer, curlier, straighter or a different color at first, and usually settles back toward your natural hair over time.
Can Scalp Cooling Help?
Scalp cooling uses a snug, chilled cap worn before, during and after each infusion. The cold narrows blood vessels in the scalp so less medicine reaches the hair follicles. According to Breastcancer.org, cold caps and scalp cooling systems have helped many people keep some or much of their hair, with results that depend on the chemotherapy medicines used. Ask your doctor whether scalp cooling suits your treatment, what it costs and whether your insurance may cover it.
Preparing Before Treatment
- Take photos of your current hair so you can match its color, length and style if you'd like to.
- Consider a shorter cut. Breastcancer.org notes that losing short hair can feel less upsetting than losing long hair, and a wig fits more easily over less hair.
- Choose your wig early. You will likely have more energy before treatment, and you can practice wearing it.
- Measure your head with a soft tape measure using our measuring guide.
- Call your insurance company before buying, to ask about coverage (see "Paying for a Wig" below).
Choosing a Wig During Treatment
Comfort matters most when your scalp is sensitive.
- Choose a soft, breathable cap. Hand-tied and double monofilament caps feel gentlest on a bare or tender scalp.
- Consider synthetic fiber. Synthetic wigs keep their style and need little care, which helps on low-energy days.
- Go a shade lighter. Breastcancer.org notes that skin tone can change during chemotherapy, so a color slightly lighter than your own hair is often more flattering. Our wig color guide explains undertones and rooted shades.
- Look for adjustable straps so you can fine-tune the fit as you go.
- Add a soft liner. Wig caps and grips help with comfort and security, and scarves, turbans and sleep caps give your scalp a break at home.

Caring for Your Scalp
- Use a mild shampoo and a soft brush while your hair is thinning.
- Protect your scalp from the sun with sunscreen or a hat, and from cold with a scarf or cap.
- Try a soft cap or satin pillowcase at night.
- Ask your care team before using new hair or scalp products.
Paying for a Wig
Many insurance plans cover part or all of a wig for hair loss from cancer treatment when your doctor prescribes it. Insurers call it a cranial prosthesis or hair prosthesis. According to Breastcancer.org, you will usually need:
- A prescription from your doctor for a cranial prosthesis, with your diagnosis code.
- A receipt for the wig that includes the seller's tax ID number.
- Your insurer's completed claim form.
Call your insurer before buying to ask what they cover and what paperwork they need. You may also be able to use HSA or FSA funds. If cost is a barrier, see Free Wigs for Cancer Patients, or call the American Cancer Society at 1-800-227-2345 to ask about local programs.
When Your Hair Grows Back
Early regrowth can be fine and uneven. Many people keep wearing a wig until they feel ready to go without one, or switch to a hair topper or a shorter wig as their hair fills in. Breastcancer.org recommends waiting a few months before coloring or chemically treating new hair, and checking with your care team first.
Caring for Your Emotional Well-Being
Losing your hair during cancer treatment can feel like one more loss at an already hard time, and every feeling about it is valid. Our guide Coping With Hair Loss: The Emotional Side offers support, and our private Facebook community, Wig and Topper Help, connects you with people who understand.
