Hi @drhill and welcome. I as well as a few others on this feed have had hair loss in the beam path from radiation only to have it grow back within a few months. For me it was a very straight line loss border so I resembled a monk from the twelfth century. I was in my fourties’ then. My beard however never grew well on the radiated side and is rather frightful during deer hunting season yet the scary appearance is my excuse for my dismal hunting results.
For you I cannot know. I understand your angst. We all will die someday but one should never die from vanity. That would be tragic. Let’s get you cured first. Then to a wig shop perhaps which in itself can be a fun experience. And after that let’s see what time brings.
Ask the doctor about the possibility of proton radiation. It is often more costly but is pinpoint compared to the vastness of photon. With the brain so close I would insist on proton. Your oncologist may not have access to a proton machine however you likely do.
I also see that the hair can be protected somewhat with a lead scalp cap or guard wrap.
How soon before this begins?
