Hi Bluedude,
I just had a HT a few days ago. Pretty happy with it so far (not that I can tell how it's gonna turn out). I had the option to not buzz my head which I chose, after we were done with the procedure it looked just hideous, so I buzzed the untouched (neither donor nor transplant side) off. After a day or so of not recognizing who is looking at me in the mirror I have gotten used to the look and actually enjoy it. I might keep it buzzed for a while until the transplanted grafts get a chance to grow in. My point is, at your age and with your progression of loss I wonder if I would even go for a HT. If I were you I'd just shave it off (you pretty much won't have any hair to speak of for about one year after a possible procedure) and see how you like it. You might get used to the look and never look back and don't have to spend the time/money/emotional distress this can cost you.
Just my 2c, evaluate all your options. You can always do it in a few years if you think that's the route you want to go.
