If you are taking Lisinopril (which I highly doubt you are), that can cause hair loss.  The same thing happened to me, I went in they did a complete work up, and found out I was anemic.  So I started taking Iron.  But don't over do it on Vitamins either because if your body is already receiving these vitamins you can cause an adverse effect.  So I would say go to a dermatologist and get a complete work up on your blood and they should be able to help you.  Once I started on Iron 130mg per day, my hair stopped falling out.  Good Luck!
