How Many Hairs Are Lost in Each Norwood Class?

Happy new year Doctor

I understand there are about 100.000 hairs on a NW1 dark haired caucasian.Is there an estimation (or even guesstimation ) on how many hair are lost per norwood scale ?

I would guess that a full Norwood class 7 patterned patient will lose 65-75% of his hair, an advanced class 6 patient would lose 50% of his hair (depending upon the degree of balding), and a class 3 pattern would vary all over the place, as the 3 pattern varies significantly between men.
