Hey Mike, some of your concerns are correct. In one HT, even the best of the best can't come close to your original hair density. The hair will match perfectly because it's your hair, but you should plan on doing it twice if you want nice density. I had my front hairline moved up 3/4ths of an inch, and had the receding sides filled in. I recently had a second HT bumping up another 1/4" bringing the move up to 1" total. It's looking killer at 4 months. One donor scar, and my wife can't even find it. That scar will never be a problem in the future. As long as you go to a good reputable doc, HT's work like a charm.
