Washing withOUT Shampoo
There are many reasons to eschew typical shampoo if you have naturally curly or wavy hair. Most shampoos contain harsh, drying sulfates that are extremely damaging for curly hair. Using conditioner, or another replacement such as baking soda in place of shampoo will cleanse the hair just as effectively without stripping it of moisture.
You need to clarify the hair of any hair products that cannot be removed without shampoo. Use a sulfate shampoo to remove any silicones or waxes in the hair. Only do this once before beginning the method! It will take 2-4 weeks for your hair to adjust to the no shampoo. It may even look worse at first. Then start washing your hair with baking soda.
