First off, I'm 17..I'm not really balding or have any bald spots. If I run a comb or my hands through my hair, usually nothing will fall out (maybe once in a small while, 1-3 pieces). However, whenever I shower..I seem to lose quite a bit or hair; I mean after I massage my scalp; my hands has ohh...quite a number of hair. This is the only time I lose so much though; it doesn't happen anywhere else. Is it normal to lose hair when you shower?
