Thanks for the comments so far.
So here are some pics of my 40 y/o noggin. You can see that I've cut my hair quite short. I leave it just long enough in the back to cover the FUT scar. I have another scar (visible/vertical) that is from a bike accident I had as a kid. I cut my hair short as it was beginning to look ridiculously thin up top and I wanted to avoid the "comb-over" look at all costs.
I have a long, big head with a lot of real estate to cover. The front of the forehead was looking particularly ridiculous with the transplants I'd had done back in 2004, so I've actually been plucking those out. I know, may sound crazy, but if you look at my head from the side, you'll see how strange it would look with that extra 1" of stubble trailing down the front.
I really like my hair short. I'd shave my head if I could, but of course that's not an option now with my FUT scar. So I'm left with the dilemma of keeping things as they are or going for a second surgery.
Thoughts?
