To neutralize the basic shampoo. Base dissolve oils, that is why a basic liquid could wash hair. But it would also remove the natural oils that make hair shiny and manageable.





If you were to check the pH of after shampoo hair conditioner, you would notice them to be slightly acidic, and to contain oils to replace the ones washed away.Some shampoos are basic. Why do people rinse their hair with vinegar after washing it?
