Curious when hair will start growing back after radiation. Have read where it should start about 3 months after radiation ends. I had a brain tumor removed Nov 2017 and started radiation in December for 6 weeks ending on February 9, 2018. Just wondering if this is accurate and should I get my hopes up or is 6 months more realistic? I hear so many different things and do not know what to believe. I am 44 and miss my hair. I kow people say, at least you have your life, I get that too, but I am very frustrated as all you see is half a white scalp and massive scarring. Would love for my nice brown hair to grow back in sooner than later. Any encouragement or help would be a ray of hope for me.
