What sort of shampoo do you use and why have you had to start washing it so often? It might be that it's getting really dried out from shampooing so much. You could try alternating washing with shampoo and washing with conditioner, where you just scrub the scalp with conditioner like you would with shampoo. I don't use any shampoo at all, except maybe once a month. Many girls on here don't shampoo very often, so you might consider a routine like that.
