When I found out that I react to other things in shampoo and toothpaste besides gluten, I decided to go No Poo.
google instructibles/How to go No Poo. It is amazing how great my hair is with two simple ingredients.
As for my teeth, I brush with baking soda and water. Just 1/2 tsp. in my hand a wet toothbrush does it. I just brush, brush, brush, until my teeth sparkle. And my mouth feels clean.
