For this lately few years, my hair keep dropping. I can't find out what is the reason makes my hair drop a lot. I've collected a lot of hair loss resources from internet, read a lot of books, do research among friends and relatives. Mostly hair will drop causes of stress, not enough sleep, unbalance food nutritions, unstable hormonce, and etc.. For those people loss their hair a lot, try do as much as information about hair loss.
