It may be bad for your hair

It is bad for your hair. Not shampooing enough can cause a buildup of your natural oils in your hair which can weigh it down and won't let it breathe. Its also bad for your skin because dirt, oils, and everything else you come in contact with will just sit on your skin.
Its best to shower every other day.

I don't agree that it's bad for your hair necessarily. Your hair adjusts itself. I'm currently on day 3 of not washing my hair and I'm leaving it until tomorrow night because every once in a while you're meant to let the natural oils build up
However, you still need to wash face, hands, underarms and between legs at the very least, twice a day to avoid any hygiene problems

These natural oils can lead skin conditions like acne vulgaris, where sebum becomes backed up in the hair follicles, creating a smorgasbord for bacteria, which break the fats into fatty acids. These create an allergic reaction that presents itself as acne.

While it isn't necessary to wash your hair everyday because that does strip your hair of these important oils, it also isn't good to go too many days without clearing those oils away because they can end up clogging pores and can cause problems.

It can be bad for the skin if you do this. Like Nicole said, it can lead to things like acne, which isn't cool. You don't have to shower every day or anything, maybe every other day or so just to get rid of the dirt and oils.
