Craig,
I'm eight years four months from my last radiation treatment, and there are still areas of my face and neck that are hairless. I'm pretty sure at this point that it's not coming back.
I had IMRT radiation, concentrated on the right side, and the hair on the right side of my face is pretty sparse, and it hasn't changed in years. There is virtually no growth below the jaw line, so the good news is that I don't have to shave my neck any more, just the left side of my face. You are right, it is a hassle to just shave one fourth of your face to keep from showing stubble on just one side. I switched to using an electric razor, so it goes much faster in the mornings.
The new normal isn't so bad...

Good Health,
Chuck
