I had hair loss from some medication (depakote or lithium I think but I was on lamictal at the same time so maybe it? too many meds). I was told to take Centrum silver and selenium and it would help. It seemed to. My hair was really thick before meds and it is not thick at all now but that could also be hormonal. If you take Centrum silver I think you have supplement folic acid if you are female and could get pregnant and you should make sure there isn't anything else. I'm certainly no vitamin expert, this is just what someone (may or may not have been a dr) told me to try.
