Think of those mornings when you hit the snooze button a few too many times, and you wake up with barely enough time to pull on some clothes and rush out the door to the office. Thanks perhaps to some perverse joke being played by the goddess of coiffures, those frantic occasions also tend to coincide with your worst cases of bed head. When the-sebaceous glands attached to your hair follicles have unleashed an oil slick worthy of the Exxon Valdez. Your 100,000 to 120,000 or so of hairs weighted down with that oil—which is really a combination of accumulated cell debris, chemical components of sweat and various tiny pieces of dirt picked up from the air- are protruding every which way, creating a look reminiscent of the lead character in the Calvin & Hobbes comic strip. Of course you don’t have time to shampoo and rinse your rebellious locks in the shower, and then dry and reshape them.

We would say try it. It does help, and there is nothing wrong with letting your hair stay un-washed for a couple days.
