I have experimented with various non shampoo systems: baking soda, no wash, dry powder, solid shampoo etc. The reason being is that I want to get rid of the preservatives in my life. I have nothing against surfacants like sodium laureth sulfate. But preservatives aren't so harmless, especially the parabens.
Recently, I have been washing my hair with a quarter cup of dry Rhassoul clay, basically making mud cake on top of my head and massaging down the length of the hair and rinsing. I do this about once a week, and I have to say that it doesn't leave my hair sticky as when I use the baking soda. It washes out really clean and silky. An added benefit is it doesn't really add anything to my waste water. No alkaline or additives go into the waste stream. I know of people who bath with it as well. I usually use it on my face as a mask, but there are so many other uses. With a little garlic oil added, I used it as a disinfectant mask on a nasty cat bite. It draws blood to the surface to aid healing.
i would probably not put any mud on a catbite, even though it is a puncture, no matter how "sterile" the mud is. The body heals faster if the wound is dry and clean rather than covered and stifled. clean water and a thorough washing is a better solution. only a bandage light enough to keep debris out, like a very thin gauze.
i like the clay idea for hair though. this summer i'm looking forward to mixing up some soap ginger shampoo.
After reading about rhassoul clay I decided to try this clay shampoo. I liked it because it is completely natural. Even my friends noticed a change, hair became stronger and more beautiful. Mpreover rhassoul clay is very useful for you skin.
