Answer 1

It depends on what kind of hair fall. In baldness the roots shrink they become crippled and malnourished not able produce a good hair follicle. With normal shedding the hair falls out and regrows normally. Normal shedding and hair loss can look very similar. Usually in hair loss more hair can be seen on the towel after shwering. In normal shedding 2-3 hairs on the towel are a sign of good hair health.
