7100 grafts look like too much. Was that performed in one session ? I do not think the guy needed 7100 grafts. Also with that amount the result should have been more dense and consistence especially at the back. Unless half of what has been transplanted have been lost.
@Rdasilva604: Not sure what you looked like before the HT but you are full of hair. Not sure what your issue could possible be. The majority of people on this forum (me included) would only dream to have the amount of hair you got.
