Does Radiation Therapy Cause Hair Loss?

Radiation therapy is a critical component in the battle against cancer, often employed to eliminate and control cancer cells within the body. It can significantly improve outcomes and enhance the quality of life for individuals facing the formidable disease. However, like any treatment, radiation therapy comes with its own side effects. One particularly challenging one is radiation-induced hair loss, also known as radiation alopecia. Here, we are going to shed light on this aspect of cancer treatment, discussing the causes, implications, coping strategies, and available support for those facing radiation-induced hair loss.

Understanding Radiation Hair Loss

Radiation Hair loss is a consequence of radiation therapy, wherein the radiation damages the hair follicles in the treatment area. This damage disrupts the normal hair growth cycle, leading to the shedding of hair in the affected region. The severity of hair loss can vary based on factors such as dosage and duration of radiation treatment and the specific area of the body receiving radiation.

The extent of hair loss during radiation therapy depends on several factors, with dosage and duration of treatment playing a crucial role. The higher the dosage and longer the duration, the more likely significant hair loss will occur. Additionally, the area of the body receiving radiation is also a determining factor. Areas with denser hair follicles are more susceptible to substantial hair loss. Hair loss may also be permanent with higher doses of radiation therapy.

Unlike chemotherapy, which impacts the entire body, radiation-induced hair loss occurs only in the treatment region or where the radiation beams penetrate. For instance, if radiation is administered to the head, it affects solely the hair follicles in the specific area. Conversely, if radiation is targeted at other body parts, like the chest, legs, or abdomen, hair loss will only occur in those particular regions, sparing the hair on the head.

Side Effects and Emotional Impact

Radiation hair loss can be emotionally and psychologically challenging for individuals. It’s not merely a physical change but a transformation that affects self-esteem and body image. Dealing with changes in appearance can trigger a range of emotions, including anxiety, depression, and loss of confidence. It’s essential for individuals experiencing radiation hair loss to seek support from professionals, support groups, and loved ones to navigate these emotional challenges.

Ways to Manage Hair Loss

Dealing with radiation-induced hair loss can be emotionally challenging, but there are several ways you can manage and cope with this temporary side effect effectively.

Cold Cap Therapy

Wear a specialized cooling cap before, during, and after radiation therapy. The cold temperature constricts blood vessels in the scalp, reducing the blood flow and the amount of chemotherapy drugs that reach the hair follicles. This way can help minimize hair loss during treatment.

Scalp Massage

Gently massage your scalp which can increase blood circulation and may promote hair regrowth. Use your fingertips to apply light pressure in a circular motion, stimulating the hair follicles.

Healthy Diet

Maintain a well-balanced diet rich in vitamins, minerals, and proteins essential for hair health. Incorporate fruits, vegetables, lean proteins, and whole grains to support overall well-being and encourage regrowth.

Wig or Hairpiece

Consider investing in a wig or hairpiece made of natural hair or synthetic material that closely matches your natural hair color and style. This can help boost your confidence during the period of hair loss.

Consider a New Hairstyle

If you’re comfortable doing so, experiment with different hairstyles that suit your current hair situation. A new haircut or style can help you feel more in control and confident.

Use Sun Protection

Protect your scalp from sun exposure by wearing a hat or using sunscreen to prevent sunburn. A sunburned scalp can be uncomfortable, especially during hair loss.

Use Laser Hair Therapy

Laser hair growth helmets, also known as low-level laser therapy (LLLT) devices, are sometimes used to stimulate hair regrowth in various conditions, including androgenetic alopecia (pattern baldness), hair loss associated with aging as well as radiation-induced hair loss. You need to consult your healthcare team if you want to opt for laser hair therapy.

Theradome LH80 PRO is the world’s most technologically advanced laser hair therapy device. Any patient can use it in the comfort and privacy of their homes. At-home laser hair therapy devices do not disrupt compliance or decrease treatment efficacy. With this approach, you can potentially reverse radiation-induced hair loss faster.
