First let me say I'm happy with my results, but I was a Norwood 5A and had 3800 grafts. I dont have great density so if someone looked at my results (a year later) they might not be too impressed, but to me it's a night and day result.
Over a year of looking on this site it appears that the "wow" results are from young guys who had a receding hair line or some thinning. I think it's safe to say for a Norwood 5 or higher you would need at least 6k+ to see a huge difference, am I wrong?
Also, I know it;s been said before here, but I feel bad for young guys who are getting transplants as it could be tough later on down the line as hair loss progresses...
