Add 13.5 oz of water to this powder and let set to make shampoo that has that familiar gel consistency. Re-use your old shampoo bottle instead of buying a new one each time. If you like liquid shampoo, this is the greenest way to get it. Each wrapper is compostable and has instructions. Ingredients: Sodium lauryl sulfoacetate*, Sodium cocoyl glutamate, Gluconolactone, Carrageenan, Sodium cocoyl glycinate, Oryza sativa starch, Xanthan gum, Maltodextrin, Sodium benzoate, Fragrance (if applicable), Sodium gluconate, Sodium chloride. *This is NOT SLS, which is an irritant. Sodium lauryl sulfoacetate (SLSA) is a mild ingredient. (This product is vegan-friendly.)
