I shower every day...I wash my hair every 3-5 days, just depending. But I will skip a Sunday shower every now and then. But I'm a sweaty person when it's hot out and I stink if I don't bathe, lol.
longest i went was probably 5 or 6 days, when i had my dreads, and i was a dirty barefoot hippie, haha. gross. so glad i'm over that. but right now i definitely need a shower, since i just got back from the gym.
My new years resolution was to take a shower every single day. This failed. It tends to be every few days... I do wash daily though...
