I no longer use soap for most of my body when I shower, I no longer use it when washing my face at night, and I no longer use shampoo. And things are fine. I once tried not using deodorant in one of my armpits. After about a week things were fine, but it got bad when I wore a tuxedo and went to a fancy dinner. I think the stress of the dinner made me sweat, and the tuxedo trapped the heat and sweat, so the bacteria went to town. Other than that sort of scenario I imagine I could get by without deodorant. My girlfriend never uses any and only rarely smells bad. It's possible that you have to wait for the bacterial population to balance out, and then the odors diminish. After you stop using deodorant, you'll get colonized by certain species that are most aggressive. But I'm guessing that over time you'll get a better mix, and better smells. Would be interesting to see more microbiome studies to investigate this.
