I minimize showering. Been doing that for years. I wash with talc/cornstartch/whatever stuff. It grabs the dirt and excessive oils off the skin just fine. Also hair as well.
Doesn’t matter if it’s wet or dry. If it gets the stale sweat and the dirt off, it doesn’t matter how.
Why do I do it that way? I dunno. I did it as an experiment once and found I liked it better than soap/water/shampoo stuff.
Some things need soap. Hands do for example. Feet. But most of the body doesn’t really get that dirty.
