everytime i shower and wash my hair, it seems like more and more of my hair is falling out. sometimes it's in clumps, other times it's less hair but still significant enough to be a problem. i'm not sure what's causing this but i'm afraid that it's only going to get worse. i have very thick and long hair and thankfully you can't really tell just by looking, but i know its thinning out slowly but surely. has anyone had a similar problem or know why this might be happening?
