I'm only 15 but my hair is falling out a lot, and the middle towards back of my head is almost balled, I got really scared when I wash my hair, and brush my hair, I could pick up chunks of my hair after I showered and blow dried it, I've never straighten my hair, and I don't style my hair a lot, my hair is really thin and straight. And I used to pull out my hair a lot, but I don't do it now, is it one of the reason? Im so stress about it.
