i don't tend to shower, ever, but... if you're a guy with short hair, it doesn't really have a major impact on you if you do or don't wash your hair every day. if you have longer hair, it's better for your hair to wash it every other day to once a week. i find it hard to go past a second day without washing it,and i usually use a dry shampoo. sometimes i'll wash it every day because it bugs me... but it's generally not good for your hair. dries it out and makes it brittle and such.
