I've stopped using soap about a year ago, because my skin was always itchting after my daily shower, I now only use it for the genitals and under the arms. No problems with smell or oily skin at all.
I'd like to to the same with shampoo, only problem is that my hair gets oily extremly fast and my hair would look like that of a hobo after two days, so a two week period to get past that is way too much for me. Maybe I should start to use only water every second day.
