Thanks, lorenzo for the thorough explanation. What I was concerned about was the possiblity of going through all of this and spending so many $$$ only to find out that you end up with no more hair on top,a scar,fewer hairs in back and a drained bank account. Are you saying that even with the best of doctors, there is a 1% chance that the ht would fail? I don't mean b/c of unrealistic expectations - I mean where the hairs just don't grow or whatever and therefore there is no net improvement in the hairline.
