Question: how do you use baking soda to wash your hair?
Answer: It takes a LOT of water to lower the pH of baking soda into the safe zone. Instead of forming a paste, we recommend mixing 1 teaspoon of baking soda in a 16-oz bottle of water. You'll end up with a cloudy solution that is still very powerful. Pour some of this solution into your hair and massage it into your scalp.
