Your oil glands are working hard, and it is most evident at the roots and at the bang area. Washing too often can be damaging; it can exacerbate already overactive oil glands and make dry hair even more fragile. Why not consider using a dry shampoo on your roots? Brush through thoroughly. Wash you bangs as often as needed to keep them fresh. Deep-condition the rest of your hair to keep it healthy. I hope that helps!
