When you guys do the no poo thing, do you mix it up ahead of time in a bottle or do you mix it each time you do your hair. It sounds like a pain to have to mix it every time. Do you mind sharing exactly how you do it. I’ve read it online and am seriously considering this as I have little pimples that turn into sores that do NOT heal. I have cut out all grains and still have them so this is my next step.
