Julius, you seem very fixated on this issue. I understand that you would want a transplant to look as close as humanly possible to a head of dense, natural hair, but really, unless a transplant is below average in density is will be thick enough to convince people that you have good hair.
I don't remember seeing your photos (if you've posted them) but surely if you're looking into getting a transplant then the realistic, achievable results are going to be an improvement on your current hair situation.
