Twice a day on work days and once a day on my days off. I'm a germophobe so I like to make sure I'm all clean after a day out in public.
I always shower daily unless I'm completely exhausted a fall asleep early or if I'm feeling really sick. Otherwise I'm always too active during my days to be able skip washing a days worth of funk off of me. I like to exercise alot and I work in a kitchen that gets very hot, so I always have plenty of sweat. I do try and stick to washing my hair every other day tho
