Even though some things are necessary for good hygiene, like everyday showering and brushing your teeth, washing your hair isn't one of them. That's right -- it's not absolutely necessary to wash your hair every time you clean the rest of your body. In fact, many hair stylists actually recommend washing it every other day or every couple of days, rather than daily.
Why? As the shampoo removes all the unwanted dirt and gunk from your hair, it also strips your locks of natural oils. And while too much of that oil can leave your hair looking greasy, in moderation it can keep your hair from drying out, help stave off dandruff and make your hair easier to style. So that's one less thing to worry about in the morning -- well, at least every other morning.
