How many hairs are transplanted in each square centimetre of scalp?

It is impossible to give an exact figure for the number of hairs transplanted per cm2 because the number can vary significantly, and depends on factors like the colour and thickness of the donor hairs. Thick, dark hair can be transplanted more sparingly than thin, blond hair with the same results in terms of appearance. The area to be treated and the desired results also need to be carefully evaluated.

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.
