If you want to skip shampooing but don't want to leave the house with stringy bangs, just wash your bangs. It's easy: pull the rest of your hair back in a ponytail, wet your hands with a small dime-size amount of conditioner, run it through your fringe, and rinse it out under the faucet. If you have straight hair, it's probably not necessary to blow-dry, as they'll air-dry in minutes. If your hair is a little more unruly, quickly blow-dry and style your bangs as you normally would.
