i have recently been shedding more hairs than seems normal. i am sure that this means a deficiency of some mineral or vitamin, which one?

It can be caused by certain medications, or from the change of seasons. I notice an increase in hair loss for a short time at the start of each season, spring, summer, etc. Or, it could be genetics.

A thyroid disorder can also cause the hair to shed..alot of women have this and never know it for years. Sam
