Yeah, I can go a whole week without washing mine and it will look absoloutely fine. I have crazy thick hair, so to be honest I procastinate like hell about it anyway as I'm committing to not only washing it but also to about 2 hours of blow drying and straightning (which never lasts, slightest bit of water in the atmosphere - frizz and waves back, and I live in the rainy city of the UK! so I can re-straighten my hair upwards of 7+ times a week XD
It's bad to wash your hair every day, and I used to. My hair just doesn't get greasy these days and I even use alot of products to make my hair more managable.
I should shave my head again.
