My boss's wife was a consultant dermatologist at the time, and she said most people wash, bath and shower far too often for their own good. The problem I have is that water, or anything containing water, makes me itch so much I scratch myself to pieces. I hate hot weather because sweat has the same effect. My hands are reasonably OK unless I am using detergent, which I am also allergic to, so a lot of bath preparations are out of the question. I use apple cider vinegar on my hair, or "white" vinegar at a pinch, with oil in the water. Ordinary vinegar makes me smell like a fish and chip shop
