Yeah, that's what is slowly starting to dawn on me. Many clinic websites showcase various celebrities who've undergone surgery but, when you delve into the details, you discover that, more often than not, they're repeat customers. This is not a realistic long-term strategy for someone in my situation.
Well you can only transplant x amount of grafts per cm2 at once without the risk for not enough blood supply for the new hair follicles, the ones who are not fully satisfied density wise often go for a smaller surgery just to add density, you can checkout my thread, 1 week after the transplant it was pretty much undetectable.
Many good Drs can dense pack the first line with up to 60-70 grafts per cm2 which will look pretty dense. I believe avg for a caucasian male naturally is about 80 grafts per cm2. It is also what your average hair per graft is that matters, some have a hair density average at 2 hairs per graft, some have close to 3 hairs per graft, which makes a huge difference. There is also a difference in the thickness of the hairs, some have a diameter of 0,45 mm like myself, some have 0,80 mm, they will have almost double density compared to me because of the hair thickness.
Another time you need more transplant is say 10 years from now your recession have travelled further, you might want to add some in the gap, other than that transplant can look very natural and do a good job at creating an illusion of density.
