Every day. Sometimes twice a day if I do sports. However, I do not wash my hair every day, or it dries out too much; instead, I wash my hair every other day. But I would feel gross if I didn't shower every day.
I usually soap off in the tub everyday - something like a bath, but I don't fill the tub up. I only shower maybe 3 times a week, when I wash my hair. My hair gets dried out if I wash it too often, and I don't usually have time for a full soak in the tub.

I shower every morning, but usually only shampoo every other shower. I condition every day, though, or my hair will be impossible to brush because it's incredibly fine and is prone to dry out and tangle, bah...
