Hair Loss and Radiation Therapy - What to Expect

Great question! The short answer: it depends on WHERE you're getting radiation.

How Radiation Affects Hair

Radiation therapy damages cells that divide quickly - that's how it fights cancer cells. Hair follicles also divide rapidly, so they can be affected. BUT - hair loss only happens in the area being radiated.

Key Points:

If radiation targets your head/brain:

  • Hair loss is likely in the treatment area
  • Usually starts 2-3 weeks into treatment
  • May be temporary or permanent (depends on dose)
  • Often regrows after treatment ends

If radiation targets other areas (chest, abdomen, pelvis, limbs):

  • Hair loss typically does NOT occur
  • Your scalp hair should be fine

What You Should Ask Your Oncology Team:

  1. "What area of my body is being treated?" (This determines hair loss risk)
  2. "Based on my radiation dose and field, should I expect hair loss?"
  3. "If I do lose hair, when might it start and could it be permanent?"
  4. "Are there any scalp cooling options available?" (Some centers offer this to reduce hair loss)
  5. "What resources do you have for wigs, scarves, or support if needed?"

Resources:

According to the American Cancer Society, hair loss from radiation is one of the most common side effects when the head is treated, and they have detailed guides on coping strategies and wig resources on their website.

The National Cancer Institute (NCI) also provides information about managing radiation side effects, including hair loss.
