for karen and others who have bangs

this thread is really what karen started about how often do you shampoo. karen mention that she washes her hair once a week. i know karen has bangs and so do i. if i don't wash my hair everyother day my bangs look gross. what do you do about the bangs? i've tried freshing them up by just washing my bangs but sometimes it's difficult just to get the bangs. sometimes the shampoo ends up in the scalp. i'm wondering when you have bangs do you wait a week to wash them? or have a easy way to wash just the bangs?
