I get it washed one week and then skip it the next.
It really depends on the type of hair you have. Like Angel said, using allot of shampoo when you don't have that much hair is a waste. Not washing it for a month, I imagine that would smell. How do you keep it from smelling? If you don't want to wash it than why not go to a salon and get it washed for you?
I mean why use as much shampoo as a long-haired girl if you only have an inch of hair, for example? That's wasting.
and if you have a buzz-cut you can use soap just as easily as shampoo
