I stopped using soap and shampoo in the shower years ago. If I'm really dirty I'll use soap--I'm not a barbarian. But in general, yeah, the skin's natural oil remains if you just take a hot shower with no soap, and, at least for me, no-one complains about BO (in fact the opposite!). I feel clean, smell clean. Interestingly, this really helped my dandruff - just rubbing the scalp with hot water completely stopped it far better than any shampoo.
