I don't use shampoo, I only co-wash. So I use 1 tablespoon of baking soda and two cups of water to clarify my hair once a month. I do a ACV rinse after every cowash or baking soda wash. I love ACV rinses bc they make your curls pop better. Also baking soda makes your hair basic and the acv rinse brings the acidity back to your hair (I think, somebody could probably explain it better). I noticed that when I starting doing ACV rinses my hair would lay down flatter.
