While chemotherapy is an effective treatment for cancer, it can also cause side effects, including hair loss.

Hair loss is a topic that can be difficult to confront, especially for those who have undergone chemotherapy. While it may not be the most glamorous subject, understanding when hair loss starts after chemo can help you feel more prepared and less anxious as you go through treatment. So if you’re wondering what to expect during this part of your journey, keep reading! In today’s post, we’ll explore the timeline of hair loss after chemotherapy and provide some tips on how to cope with this common side effect.

What is Chemotherapy?

Chemotherapy is a type of cancer treatment that uses drugs to kill cancer cells. Chemotherapy can be given intravenously (through an IV), orally (in pill form), or topically (as a cream or lotion). The drugs enter the bloodstream and travel throughout the body, killing cancer cells that have spread to other parts of the body.

While chemotherapy is an effective treatment for cancer, it can also cause side effects, including hair loss. Chemotherapy drugs attack all rapidly dividing cells in the body, which includes hair follicles. As a result, patients may experience hair loss on the scalp, face, arms, legs, and even in their eyebrows and eyelashes. Hair loss typically begins 2-3 weeks after starting chemotherapy and may continue for several months after treatment has ended.

Some patients choose to wear a wig orHat during treatment to cover up their hair loss. Others may opt for cold caps or scalp cooling devices, which are worn before and during chemo treatments to help prevent hair loss. Talk with your doctor about your options for managing hair loss from chemotherapy.

Understanding the Hair Loss Process After Chemo

There are a few different ways that chemotherapy can cause hair loss. The most common way is by causing the death of rapidly-growing cells, including those in the hair follicles. This can lead to the shedding of existing hair and the prevention of new hair growth. In some cases, chemo may also damage the cells that produce pigment, leading to changes in hair color.

Hair loss from chemo is typically gradual and may not be noticeable until a few weeks after treatment has started. In some cases, all of the hair on the head may be lost, while in others only patches may be affected. Some people may also experience thinning or changes in texture.

The good news is that hair loss from chemo is usually temporary. New hair growth usually begins within a few months after treatment has ended and eventually returns to its pre-treatment state. However, it is important to note that some people may experience permanent hair loss or changes after chemo.

Causes of Hair Loss After Chemo

Hair loss after chemo can be caused by a number of factors. The most common cause is the chemotherapy itself. Chemotherapy drugs attack all rapidly dividing cells in the body, including cancer cells and healthy cells. Hair follicles are among the fastest-growing cells in the body, so they are particularly vulnerable to the effects of chemotherapy.

Other potential causes of hair loss after chemo include:

• Side effects of other cancer treatments: Radiation therapy and certain types of surgery can also damage hair follicles and lead to hair loss.

• Stress: The physical and emotional stress of dealing with cancer can cause hair loss.

• Nutritional deficiencies: Cancer and cancer treatments can sometimes cause nutrient deficiencies that lead to hair loss.

Signs and Symptoms of Hair Loss After Chemo

One of the most common side effects of chemotherapy is hair loss. While this can be a distressing and emotionally difficult symptom to deal with, it is important to remember that hair loss is usually only temporary. In most cases, hair will start to grow back once treatment has finished.

There are a few different ways that chemotherapy can cause hair loss. The first is by directly damaging the cells that make up the hair follicles. This type of damage usually affects all of the hair on the body, not just the scalp. Chemotherapy can also cause an imbalance in the hormones that control hair growth, leading to shedding and thinning.

The timing of hair loss after starting chemotherapy varies from person to person. It can happen anywhere from a few days to a few weeks after treatment begins. In some cases, baldness may not occur until several months into treatment. There are a few things that can help manage or prevent hair loss during chemotherapy:

-Cold caps or headscarves: These products can help reduce blood flow to the scalp and minimize hair loss.

-Medications: Your doctor may prescribe medications such as minoxidil (Rogaine) or finasteride (Propecia) to help stimulate hair growth and slow down shedding.

-Nutrition: Eating a balanced diet with plenty of protein, iron, and other nutrients is important for keeping your hair healthy during treatment.

Treatment Options for Hair Loss After Chemo

There are a few different ways to treat hair loss after chemo. One option is to use a cold cap, which can help to reduce the amount of chemotherapy drugs that reach the hair follicles and prevent hair loss. Another option is to take a medication called minoxidil (Rogaine), which can help to stimulate hair growth. There are also a number of wig and hairpiece options available for people who are experiencing hair loss after chemo.

How to Properly Care for Your Hair During Chemotherapy

Hair loss is a common side effect of chemotherapy. Whether you are undergoing treatment for cancer or another condition, there are steps you can take to care for your hair during chemotherapy.

Before treatment begins, talk to your doctor or nurse about the possibility of hair loss. They can help you choose a wig or other head covering that is right for you. They may also recommend products to help reduce breakage and protect your scalp.

During treatment, be gentle with your hair. Avoid harsh chemicals and heat styling. Instead, opt for gentle cleansing and conditioning products. You may also want to avoid tight hairstyles such as ponytails, buns, and braids.

After treatment is finished, your hair will likely grow back. Be patient as it may take several months for it to return to its pre-chemo state. In the meantime, try different styles and products to find what works best for you.


Hair loss after chemo can be difficult to deal with, both physically and emotionally. However, it is important to remember that hair loss is a side effect common in many cancer treatments and usually begins 2-3 weeks after chemotherapy starts. Luckily, the process of regrowing your hair normally begins 3-4 months after the last chemotherapy session has been completed. Although temporary, there are several ways you can use to manage this difficult experience such as getting a wig or finding alternatives for handling bad hair days.
