When facing radiation therapy, one of the most common questions people have is about hair loss. It’s a valid concern, as our hair is often tied to our identity and sense of self. The answer, however, isn’t a simple yes or no. It truly depends on where on your body you are receiving treatment.
Radiation is a localized treatment, meaning it only affects the specific area being targeted. The high-energy beams are designed to damage rapidly dividing cells, which includes cancer cells. Unfortunately, hair follicle cells also divide quickly, making them susceptible to damage from the radiation.
When Hair Loss is Likely to Happen
You will only lose hair in the area where the radiation beams are directed. For example, if you are receiving treatment for a brain tumor, you will likely lose hair on your head. If the treatment is on your chest for lung cancer, you might lose chest hair, but the hair on your head will remain. The dose of radiation and the number of treatments also play a significant role in the extent of hair loss.
Caring for Your Scalp and Skin During Treatment
If you are losing hair in the treatment area, being gentle with your skin is crucial. Use a mild, fragrance-free shampoo and lukewarm water. Pat the area dry instead of rubbing it. It’s also best to avoid harsh chemicals, hot styling tools, and tight hats that can cause irritation. Your radiation team will have specific recommendations for you.
What to Expect as Your Hair Grows Back
For many people, hair does begin to grow back after radiation treatments have ended. This process can take several months. When it first returns, your hair might be different than before—perhaps a different texture, color, or thickness. It may be curlier or finer. In some cases, especially with very high doses of radiation, the hair loss can be permanent.
Finding Support and Embracing Your Journey
Losing your hair can be an emotional experience. It’s okay to have feelings about this change. Many people find comfort in choosing a wig, scarf, or hat that makes them feel good. Talking with a counselor or joining a support group with others who are going through similar experiences can also be incredibly helpful. Remember, this is a part of your treatment journey, and there is a whole community ready to support you.
While hair loss from radiation is a common and understandable concern, it’s important to remember that it is often a temporary side effect of a treatment aimed at healing. Having an open conversation with your healthcare team will give you the clearest picture of what to expect for your specific situation, allowing you to prepare and feel more in control.
