Dear TTP,
I have not replied to date since I was a bit befuddled when comparing your photographic results to the title of this thread.
First off, given the level of your hairloss pre-HT, and the condition of the existing hairs, it was likely that the native hair where you had the new grafts placed were going to be sacrificed since they were likely on their way out. Thus, the net of your first transplant (as was with mine) would be the difference. With that said, personally I think you have a great foundation going forward with very little use of your donor supply, especially at your age (I believe similar to mine again).
I would wait the 12 months then go see a good FUE doc for 1500 FUE or more, a year from then you will be a happy man.
Best wishes.
