Why Do You Lose Hair During Chemotherapy?
For many, the physical transformation associated with hair loss is one of the most visible and traumatic side effects of chemotherapy. Chemotherapy drugs are powerful agents that attack rapidly dividing cells, a hallmark characteristic of many types of cancer. However, the drugs don’t distinguish between cancer cells and other quickly dividing cells in the body, such as those found in hair follicles. This similarity in cell behavior leads to the unintended consequence of hair loss for patients undergoing treatment. Understanding why this occurs is an essential first step in exploring ways to potentially preserve hair, such as through scalp cooling and cold capping technology.
Why Hair Loss Happens
Chemotherapy is a treatment method that aims to kill or slow the growth of cancer cells, which divide more quickly than many of the body’s other cells. The drugs used in chemotherapy are designed to target cells with high division rates, making them particularly effective against cancerous growths. Unfortunately, our bodies contain other types of cells that also have a high division rate, especially those found in the hair follicles. This overlap in cell behavior between cancer cells and hair follicles means that chemotherapy drugs cannot differentiate between the two, leading to hair follicle damage and, eventually, hair loss.
Each strand of hair on your body grows from a follicle, a tiny pocket under the skin that contains cells responsible for hair growth. The cells in these follicles divide rapidly to produce new hair. When chemotherapy drugs circulate through the bloodstream, they disrupt the function of these rapidly dividing cells, impairing their ability to produce hair. As a result, hair growth slows or stops altogether, and hair that is already present becomes weak and prone to falling out.
When Hair Loss Typically Occurs
Hair loss, known medically as alopecia, does not usually begin immediately after starting chemotherapy. For most people, hair loss begins within one to three weeks after starting treatment, depending on the type and dosage of chemotherapy drugs used. Some individuals may experience a gradual thinning, while others may notice clumps of hair falling out more suddenly. The scalp is the most common area for hair loss during chemotherapy, but it can also affect hair on other parts of the body, such as eyebrows, eyelashes, and body hair.
The extent and pattern of hair loss depend on multiple factors, including the specific chemotherapy regimen, dosage, frequency of treatments, and individual variability. Some chemotherapy drugs are more likely to cause hair loss than others. For example, medications like Cyclophosphamide, Doxorubicin, and Paclitaxel are more commonly associated with substantial hair loss.
Psychological Impact of Hair Loss
Hair loss can profoundly affect an individual’s emotional and psychological well-being. For many, hair is closely tied to personal identity and self-image. Losing hair can make it more challenging to keep the diagnosis private and serves as a constant reminder of one’s health struggles, adding to the emotional weight of the treatment process. The change in appearance can lead to feelings of sadness, anxiety, and loss of confidence, impacting social interactions and overall quality of life. Recognizing these emotional challenges is crucial, as it underscores the importance of exploring available options to help preserve hair during chemotherapy.
The Role of Scalp Cooling and Cold Capping
Given the psychological and emotional challenges associated with hair loss, many patients look for ways to reduce or prevent it during chemotherapy. One promising approach is scalp cooling, also known as cold capping, which involves cooling the scalp to constrict blood vessels and limit the amount of chemotherapy drugs that reach hair follicles.
Scalp cooling is a proven method for reducing hair loss in many chemotherapy patients. It works by gently cooling the scalp with a specialized cap before, during, and after chemo sessions. This cooling effect constricts blood vessels, limiting the amount of chemotherapy medication that reaches the hair follicles. By protecting these cells, scalp cooling can significantly increase the chances of keeping your hair.
While individual results may vary, scalp cooling has been helping people retain their hair during chemotherapy for over 25 years. If you're concerned about hair loss, talk to your doctor about whether scalp cooling is right for you.

Exploring Cold Capping Options
Cold capping, while not guaranteed to prevent hair loss, is a viable treatment option that patients can consider as part of their treatment plan. There are different types of cold caps available, ranging from manual caps to those connected to machines that maintain a constant temperature. Some facilities offer scalp cooling systems as part of their treatment options, while others allow patients to bring their own cold caps to sessions. Working with a provider familiar with cold capping options can help patients navigate their choices and maximize the effectiveness of this technique.

Moving Forward with Knowledge and Support
Hair loss during chemotherapy can feel overwhelming, but understanding the reasons behind it and the available options to help manage it can empower patients facing cancer treatment. At The Polar Shift, we aim to raise awareness about scalp cooling and cold capping, helping individuals feel more informed and prepared. With the right information and resources, patients can make decisions that support their emotional and physical well-being, whether it’s exploring scalp cooling or finding support groups and resources for coping with hair loss.
Remember, every individual’s experience with chemotherapy is unique. Exploring options like scalp cooling, connecting with supportive communities, educating yourself and maintaining open communication with healthcare providers are all valuable steps in navigating this challenging journey.
