Thanks man for this. I do not need to lower hairline, I just want to fill-in temples. However, the doctor that I am interested in (Erkan Demirsoy) wants the head to be shaven, apparently for best quality. I haven't contacted him yet, this info is from the research I did. He may do exception.
I can't grow hair like this guy Legends, I would have to wear a military style (back and sides shaved with much longer bangs), the problem is then the donor area. After a month it will still be visible I guess.
