There was a massive thread about this on another forum I visit. It was more along the lines of shampoo and soap and other products that we are all sold to make ourselves clean and stuff in the shower/bath rather than not bathing
Essentially it seemed that you were better off without it all. Washing is still needed obviously but all those products aren't as they just remove all the stuff your body is pumping out trying to clean itself. It can take a week or so for your body to get its balance back apparently but once it does they found their skin was better, hair was less dandruffy (if they had a problem with it) etc etc.
A few people who needed prescription shampoo found that they didn't actually need anything, It was just that the prescription shampoo to fix scalp issues which had only come up because they tried using other shampoo which cause issues.
The only product I use in the shower is shampoo.
