Ok, posted 2 pics in the names/faces thread. Here's another one that shows how metal I 'was'... But I don't have my hair anymore, and I've got a full chin goatee now (Had to shave off the bottom because I wore a respirator while working before I went into Chemo).
I know it won't be much consolation when headbanging to Manticora, but you probably won't even notice your hair growing back. You'll look in the mirror one day and be like, whoah, it's long again. I cut mine pretty short last summer, and it's grown back pretty fast.
All the best with headbanging to Manticora, even without the hair.
