If you are too depressed and not getting good nutrition/sleep etc that can affect your hair. Mine has been coming out too b/c I'm living on cereal, hardboiled eggs, oatmeal and yogurt plus whatever my mom feeds me.

Centrum Silver sometimes helps with hair loss (it's helping me now). I think it is the selenium in it. Biotin can also help although I do not know where that information comes from so you might want to google it before believing it (I think my old stylist but I really am not sure).
