I've had 2 procedures with Bosley,2000 grafts each time. I would be completely bald back to the crown without them. It's very painful in the days after for me but my pal had the same procedure twice with the same doctor as me and only the second one as bad. I got Quasimodo like swelling and black eyes each time.
After all that, I still think it's 100 per cent worth the money....
