I posted this in another forum but it seems more appropriate here. I prefer rhassoul clay as a shampoo or "hair mask" as some call it. After giving the baking soda/vinegar method two months and only getting gooey straw textured hair for it, I had to try something else. I do believe everyone's accounts of getting good results with the baking soda, but hair texture and water alkalinity can change results I believe. I have thin hair, and I think our water is alkaline.
That being said, I wonder about the wisdom of putting something that has a very high ph (baking soda) on hair that is naturally healthy at a low ph, which, of course, explains the need for apple cider vinegar (very low ph) that brings down the ph back to a normal range. For all the bad things shampoos have: parabens (preservatives linked to breast cancer in French studies) and it's drying factor (shampoos are basically solvents), shampoos actually have a low ph, much friendlier to the hair and scalp than even the mildest form of soap or baking soda.
I shampoo once a week with my shower, and I take a handful of dry mud and place it on the top of my head and wet it under the shower head into a muddy mass and massage down the length of the hair adding water as needed. Actually, nothing more than water would probably be the best thing to do for hair, but I sure do love the silkiness of the the mud as it slithers down my body and makes me feel all wonderful and nice.
What I find ironic is that Americans spend so much money taking the oil out with shampoo, then putting it back in via hair product, just to get the look of hair that looks stiff and together like someone who never did anything to their hair to begin with.
