Why radiation causes hair loss?
Radiation causes hair loss by targeting and destroying rapidly dividing cells, including hair follicles. "Radiation therapy targets rapidly dividing cells, including cancer cells. Unfortunately, hair follicles are also rapidly dividing, making them susceptible to damage from radiation. This damage disrupts the normal hair growth cycle, leading to hair loss," explains Dr. Harikiran Chekuri.
Radiation therapy delivers high doses of radiation to cancerous cells to prevent them from growing and dividing.
However, it also affects healthy cells like hair follicles, which are among the most active in terms of division and growth. When these follicles are damaged or destroyed, hair loss, or "alopecia," occurs.
Hair loss from radiation is typically localized, happening only in the treated area, unlike the widespread hair loss from some chemotherapy treatments. Understanding this process can help in finding appropriate treatments and support.

How to choose the best shampoo for hair loss after radiation
Choosing the best shampoos for hair loss after radiation is crucial for promoting healthy regrowth and soothing the scalp. "The key is choosing an all-natural formula without harsh chemicals that can further irritate the scalp. Argan oil, in particular, has anti-inflammatory effects and stimulates hair follicles," says Dr. Kristopher, MD, FACS.
Look for shampoos that are free from sulfates, parabens, and artificial fragrances, which can exacerbate scalp sensitivity.
It's important to be patient, as new hair growth can take 3-6 months of consistent use. Dr. Kristopher also recommends that "some of my patients have found taking a hair vitamin or using coconut oil on the scalp in between washes helps."
By choosing gentle, nourishing products and incorporating beneficial oils and vitamins, you can create an optimal environment for hair recovery and growth.
How to take care of hair during radiation therapy?
Radiation therapy can impact hair health, but proper care can help protect your hair and scalp. Memorial Sloan Kettering Cancer Center recommends the following:
- Gentle Cleansing: Use mild, sulfate-free shampoos with nourishing ingredients to maintain natural oils and prevent dryness.
- Avoid Excessive Heat: Let hair air-dry and avoid heat styling tools. If necessary, use the lowest heat setting and avoid tight hairstyles.
- Scalp Protection: Wear a hat, scarf, or cap to shield your scalp from the sun and harsh weather, preventing dryness and irritation.
- Natural Treatments: Moisturize with natural oils like coconut or almond oil to soothe dryness and discomfort.
Conclusion
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.
FAQs
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.
