I chose FUE because I really didn't want the linear scar, but if I had to do it over again, I would probably get the scar to reduce risk of transection.

As for PRP, I have no personal experience with it. Some say they've seen changes in density for the better, but others seem to react poorly and go through a telogen effluvium shed.There's more concrete science behind Acell. But you have to remember, this seems to be the case with all treatments. Minoxidil, finasteride, laser, etc. Some say it helps, some say it destroyed their hair. This whole thing is a personal trial and error game until something more ubiquitous hits the market. Propecia as the best line of defense in 2016 is really embarrassing as far as progress goes.
