Why would one want to do this anyways, I don't think it would prove anything?
Hair shedding is a wildly fluctuating phenomenon that can be triggered by all manner of causes. Nobody sheds hairs at a constant rate. It would take daily observation over the course of years to come to any definitive conclusions.
It's not about how much hair you shed... even non-male pattern baldness people shed hair and go through aggressive sheds. The difference is that with non-male pattern baldness people, the hair grows back in its same thickness wheras with male pattern baldness people, in their male pattern baldness areas, it grows back more thin.
