My DFD15 has fine straight hair that grows quickly and often has frizzy new hair at the top of her head. She feels self conscious about it after a bit of teasing at school where the girls told her it looked like someone had rubbed a balloon on the top of her head to generate static 
Can anyone recommend a product that might help that won't leave her looking like she's got really greasy roots. Hairspray doesn't seem to make any difference.
