I don't shampoo at all. It gives me insane dandruff for some reason when I do. I use a very small amount of soap. It's not that big a deal because I keep my hair short. When it gets longer, than I pay the price for shampooing. I have insanely thick hair, and if I shampoo it then it basically turns incredibly poofy and turns into an afro that can't be tamed unless I use gel, but then I look like a guido, and that doesn't fly.
