How many grafts will it take to cover 1 square inch?

That is very difficult to answer without seeing you. This is because the amount of grafts required will ultimately be dependant upon the texture and quality of your hair (i.e. Darker, coarser hair may require less grafts to cover the same area, as compared to lighter colored, fine hair).

It will also be dependent upon your density goals. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
