Ever since I was about 5 (I'm 14 now) I've had these white flaky scabs in my head. It looks like dandruff so that's what I tell people but its not. I can run my hand through my hair and feel the bumps on my head. They don't hurt or anything. It's spread a little bit to small sections behind my ears. I've used a certain medication twice and a certain shampoo recommended from my pediatrician but nothing helped.
