How to manage hair loss during chemotherapy?

 

Hair loss, also known as alopecia, is one of the most visible—and often one of the most distressing—side effects of chemotherapy, particularly for women. Will I lose my hair? Is the hair loss temporary? When will my hair grow back? Is there anything I can do to prevent or reduce it?

To help answer these questions, we have compiled the answers to the 10 most frequently asked questions about chemotherapy and hair loss.

A quick note: the effects of chemotherapy vary from person to person. Always consult your healthcare team for advice tailored to your specific situation.

 

 

Why will I lose my hair?

Chemotherapy works by targeting rapidly dividing cells. While its primary goal is to destroy cancer cells, it can also affect healthy cells that divide quickly, including those in hair follicles. As a result, hair loss may occur on the scalp as well as on the eyelashes, eyebrows, and other areas of the body.

 

Will I lose all my hair?

Not necessarily. Hair loss during chemotherapy is not inevitable and varies from person to person. Several factors can influence the extent of hair loss, including the type and dose of medication, the duration of treatment, and individual sensitivity.

Your healthcare team will be best able to advise you on whether hair loss is likely with your specific treatment. Even among people receiving the same chemotherapy regimen, some may experience more hair loss than others.

The amount of hair loss depends on several factors:

• Type of medication
• Dose of medication
• Combination of medications (chemotherapy regimen)
• Method of administration (intravenous, oral, topical)
• Duration of treatment

Is hair loss permanent?

No. In most cases, hair loss caused by chemotherapy is temporary. Once treatment is completed, hair will gradually begin to grow back.

 

When will I lose my hair or body hair?

Alopecia usually begins two to three weeks after the first chemotherapy session. Hair loss may occur gradually or quite suddenly—sometimes even overnight—and can be accompanied by scalp sensitivity, itching, or tingling sensations.

 

How can I prevent or slow down my hair loss?

There is currently no guaranteed way to prevent chemotherapy-related hair loss. However, scalp cooling caps may help reduce hair loss for some people.

If you can tolerate the intense cold, a cooling cap may help slow or reduce hair loss by lowering the temperature of the scalp and reducing blood flow to the hair follicles during treatment. Effectiveness varies depending on the type of chemotherapy and individual factors, so it is important to discuss this option with your healthcare team.

 

How should I care for my hair during my chemotherapy treatments?

During chemotherapy, it is important to treat your hair gently.

• Don't wash them too often. Try to reduce the frequency of washing to twice a week. Ideally, wash your hair the day before your session and only wash it again three to eight days later, when the bulb has regenerated.
• Use a gentle shampoo, non-greasy, in small quantities and rinse with lukewarm water. Gently massage your scalp – without rubbing. Do not use baby shampoos. They are much too greasy. Pat your hair dry rather than twisting or rubbing it.
• Use a soft-bristled brush or a wide-toothed comb to style your hair gently. Avoid harsh brushes, curling irons, flat irons, heated rollers, and hair dryers. Let your hair air dry.
• Sleep on a satin pillowcase or wear a small nightcap.
• Avoid the sun, hair dyes, highlights, straightening, and perms.

Should I cut or shave my hair before it starts to fall out? 

While it is not necessary to cut your hair or shave your head, many women choose to do so. Some opt for a shorter transitional haircut before treatment begins, which can make hair loss feel less overwhelming. When their hair starts to fall out, they may then choose to shave it. Others prefer to shave their head before treatment begins, as it gives them a greater sense of control.

If you decide to cut your hair, consider scheduling an appointment with your hairdresser before your first chemotherapy session. If you choose to shave your head, it is generally recommended to leave one to two centimeters of hair.

A helpful tip: if you decide to shave your head, use electric clippers rather than a manual razor. A manual razor may increase scalp sensitivity, itching, or tingling. If you are not comfortable using clippers yourself, ask an experienced person for help or schedule an appointment with one of our partner-salon.

When will my hair start to grow back after chemo?

Hair regrowth may begin immediately after treatment ends or take several months. In some cases, new hair may even start growing before or during the final chemotherapy sessions. On average, hair grows about one centimeter per month.

Good to know: wigs, caps, turbans, and chemo headscarves do not interfere with hair regrowth. Your hair will grow back at the same rate whether your head is covered or not.

As your hair grows back, it may be more fragile or have a different texture than before. Continue caring for it with gentle, appropriate hair care products. Until your hair returns to its usual condition, it is best to avoid chemical treatments such as perms, coloring, or chemical straightening.

 

Will my hair be the same after chemo?

Unfortunately, hair that grows back after treatments is often different. The color is slightly different (it is often darker) and the texture changes. Sometimes hair grows back finer or thicker, straighter or curlier. These changes are usually temporary. It will often take a little over a year to get back your "true" hair. Sometimes, these changes prove to be permanent.

 

How should I care for my scalp?

Even after hair loss, it is important to continue washing and moisturizing your scalp. Use a gentle shampoo and follow with a moisturizer or nourishing oil to help prevent dryness and itching.

You can gently massage your scalp with your fingertips using sweet almond, argan, evening primrose, or wheat germ oil. A few minutes of daily massage may help stimulate the scalp and promote a sense of well-being during regrowth.

When outdoors, protect your scalp with a hat, cap, turban, or headscarf. You may also wish to apply a high-SPF sunscreen to exposed areas. Whenever possible, avoid prolonged exposure to extreme heat or cold, as a sensitive scalp may be more vulnerable to temperature changes.

 

What should I do if I lose my nose hair and eyelashes?

The loss of nose hair and eyelashes can lead to a few unexpected inconveniences. Fortunately, there are simple ways to manage them.

My nose is runny or bleeding.
Try rinsing your nasal passages once or twice a day with a saline solution. You can also apply a water-based nasal gel or ointment one to four times a day, especially before bedtime. These products are available over the counter at most pharmacies.

My eyes are sensitive or irritated.
Artificial tears can help keep your eyes comfortable and hydrated. Apply them several times a day, or as recommended by your healthcare provider. These products are also available over the counter.

Sweat irritates my eyes.
Wearing a cap, hat, turban, or headscarf can help absorb perspiration and prevent sweat from running into your eyes, making outdoor activities and warm weather more comfortable.

Hair Loss and Chemotherapy: In Conclusion

Hair and body hair loss during chemotherapy can be emotionally challenging and may affect self-confidence, as it is one of the most visible side effects of treatment. For many women, losing their hair can be one of the most difficult aspects of the cancer journey.

While there is no way to completely avoid hair loss in every case, there are many ways to manage this transition with confidence and comfort. By caring for your scalp, adopting gentle hair care practices, and exploring solutions such as wigs, headscarves, turbans, or caps, you can navigate this period in a way that feels right for you.

Remember that hair loss is temporary and that, in time, your hair will begin to grow back. Most importantly, remember that every experience is unique. Always consult your healthcare team for advice tailored to your personal situation and treatment plan.
