I don't really know much about the product free method, but I think there's a thread somewhere on here about water washing, which is similar, if not the same thing. I'll look for it. Hopefully, there are others who can answer your question. (Oh, and the fact that you don't brush isn't awkward! Lol!)
Curly and PROUD!!!
My hair has a mix of low/med/high porosity, and it's medium textured (some are still fine, though!)
