Why radiation causes hair loss?

Radiation therapy targets and destroys rapidly dividing cells, including cancer cells. Unfortunately, hair follicles – responsible for hair growth – are also rapidly dividing cells, making them susceptible to the damaging effects of radiation. This leads to hair loss in the treated area.

Radiation therapy is a precise tool in the fight against cancer, delivering high doses of radiation directly to cancerous cells to prevent them from growing and dividing. 

However, its precision does not always spare healthy cells with similar growth characteristics to malignant ones. 

Hair follicles, among the most active cells in terms of division and growth, often get caught in the crossfire. When radiation damages or destroys these follicles, hair loss or "alopecia" occurs. 

It's important to note that hair loss from radiation is typically localised, meaning it usually only happens in the area where the radiation is directed, unlike the more widespread hair loss seen with some chemotherapy treatments.

How to take care of hair during radiation therapy?

Radiation therapy, essential for many cancer patients, can affect hair health. By adopting certain hair care practices during this challenging period, one can navigate the side effects better, preserving the health and integrity of the hair and scalp. 

The renowned Memorial Sloan Kettering Cancer Center offers guidance for individuals wanting to maintain their hair health during chemotherapy. They recommend:

Gentle cleansing

Choosing the right shampoo is crucial. Look for mild, sulfate-free shampoos that contain nourishing ingredients. 

These products help maintain the scalp's natural oils and prevent further dryness or irritation, making them ideal for hair under the stress of radiation therapy.

Avoid excessive heat

Hair weakened by radiation can be further damaged by heat. It's best to let hair air-dry naturally and avoid using heat-based styling tools. 

If you must use a hairdryer, opt for the lowest heat setting. Also, avoid hairstyles that require tight pulling or excessive manipulation, such as tight braids or ponytails.

Scalp protection

The scalp can become especially sensitive during radiation therapy. Protecting it from external elements becomes paramount. 

Wear a hat, scarf, or cap to shield your scalp from the sun's harmful UV rays when stepping out. This not only protects from potential sunburn but also helps in retaining moisture. 

This protective layer can also offer warmth during colder months, preventing further dryness.

Natural treatments

To moisturise the scalp, consider using natural oils, like coconut or almond oil. These oils can provide nourishment and alleviate some of the dryness and discomfort.


Hair care during chemotherapy can be an emotionally and physically challenging journey. 

Still, with the proper guidance and a proactive approach, navigating this phase with confidence and resilience is possible. 

Furthermore, embracing change, experimenting with new styles, or even adopting wigs can offer a renewed sense of self. 

While chemotherapy's effects on hair are often temporary, the strength and adaptability one develops during this period are lasting traits that speak volumes about the indomitable human spirit.


How can I fortify my hair during chemotherapy sessions? 

According to Macmillan Cancer Support from the UK, to maintain and strengthen hair during chemotherapy:

  • Use a non-medicated shampoo to untangle hair.
  • Refrain from using hair dyes, bleach, hairdryers, and curling irons.
  • Use a wide-toothed comb for wet hair.
  • Wear a hair net while sleeping to gather fallen strands. Always consider discussing with your medical practitioner for personalized advice.

Which shampoo is recommended for hair regrowth post-chemotherapy? 

Breastcancer.org suggests that while shampoos are designed for thinning hair to tackle mild to significant hair loss, volumizing shampoos can also give hair a fuller appearance. It's beneficial to consult a doctor about hair regrowth shampoos suitable for individual needs.

What should I apply to my scalp during chemotherapy? 

According to Cancer Research UK, while wigs can cover the head, they might not be comfortable, especially during hotter months, due to potential itchiness and warmth. Alternatives include hats, scarves, or baseball caps. Another avenue to explore is cold caps, devices that cool the scalp, consequently reducing blood circulation.
