What to Expect During Chemotherapy and Hair Loss
Not all chemotherapy treatments cause hair loss. Your doctor will let you know whether your treatment is likely to lead to hair loss so you can plan ahead — emotionally and practically. Knowing what to expect can help you prepare for solutions like head coverings or gentle hair loss management strategies.
For many, hair is deeply tied to identity. Losing it during a difficult time like cancer treatment can bring emotional stress. BBC presenter Victoria Derbyshire once described hair loss as the most difficult part of her cancer journey — not uncommon among those undergoing chemotherapy.
Discussing your concerns with your care team and mentally preparing yourself can make a big difference in how you experience this part of treatment.
Why Does Chemotherapy Cause Hair Loss?
Chemotherapy drugs target fast-dividing cancer cells, but they also affect other rapidly growing cells — including those in your hair follicles. This can lead to thinning hair, bald patches, or complete hair loss on your scalp and body, including eyelashes, eyebrows, and body hair.
Hair loss usually begins two to four weeks after treatment starts and continues throughout treatment and sometimes for a few weeks afterward. Most hair loss from chemotherapy is temporary, with regrowth starting around three to six months after treatment ends — although the new hair may initially be different in texture or colour.
Is Chemo Hair Loss Permanent?
In most cases, no. Hair regrows after treatment, though it may appear different at first — curlier, finer, or even grey. This is usually temporary.
What Should You Expect?
You might notice clumps of hair in your brush, on your pillow, or in the shower. This can be emotionally difficult, so we recommend preparing mentally and having comfortable, soft headwear ready to support you during this phase.
Some people choose to cut their hair short in advance, which can make the transition easier and reduce the visual impact of hair loss.
Can Hair Loss Be Prevented?
While there is no guaranteed way to prevent hair loss during chemotherapy, scalp cooling caps (also known as scalp hypothermia) can sometimes help. These reduce blood flow to the scalp during chemotherapy, lowering the amount of drug that reaches the hair follicles. Results vary, and some people experience discomfort or headaches from the cooling effect.
How to Prepare for Chemo Hair Loss
- Be gentle with your hair: Avoid dyeing, perming, or using heat tools before and during treatment.
- Use soft brushes and mild shampoos: Treat your scalp kindly.
- Consider cutting your hair short: This makes shedding less dramatic and easier to manage.
- Think about shaving your head: Some people find it empowering and it may reduce irritation from shedding.
- Keep your scalp protected: Use sunscreen, hats, or soft headwear to guard against sun and cold.
Following Treatment
Your new hair will likely be fragile. Avoid harsh styling or colouring for the first few months. Consider wearing headwear while it grows in — this gives your hair time to recover and may help with your confidence.
Using Headwear During Hair Loss
Covering your head is a personal choice. Some people wear wigs to maintain their usual look, while others opt for comfortable turbans, bamboo sleep caps, or simply go without any covering. Even if you wear a wig, we recommend having a bamboo sleep cap or lightweight cancer hat on hand — wigs can feel heavy or uncomfortable, and breathable options offer relief and style throughout the day.
We recommend head scarves or bamboo caps for sensitive scalps. These are light, breathable, and easy to wear.
You're Not Alone
Hair loss during chemotherapy is one of the most visible — and emotionally complex — side effects of treatment. But it’s also one you can prepare for. With the right headwear and a little support, you can navigate this journey with grace and strength.
