So, the soap behaves just as advertised. Obviously I am not testing it for pathogens and whatever. But it literally goes on as a lotion that you rub on repeatedly until all of the little globs of dirt fall off.
I bought the bundle but I haven't tried the little scrubber thing yet.
I did, however, go to investigate the dry shampoo but I didn't realize that the cap just pulled straight off and I unscrewed it instead. Don't do that. Not recommended to unscrew. It's a bit messy. Just pull the cap right off of the bottle!
