Well, logically what you say doesn`t make any sense as most really bald people are not candidates for hair transplantation. So HT doctors that are very high Norwood's know better than to even try. Some doctors have had horrific hair transplantation work, for instance, Puig and if anyone saw it beforehand they certainly would not have the procedure performed. Since that time most of the work has been corrected but before that, you never met the doctor only the consultant and that was exactly the reason.
Harris is a very high Norwood and his result is a good indication of what can be achieved with limited door and that is very limited results so I'm sure that is a be drawback for him in selling.
In my opinion, eyelid/bag surgery is much different as one is not depending on some limited resource so yes I`m looking at the doctor`s own eyes and in my opinion, it would be like taking health, nutrition and weight loss advice from an out of shape obese individual probably not the best choice.
Just an opinion though it doesn't mean that I'm right.
