Sulfates are detergents commonly found in cosmetic and household cleaning products. Sulfates act on the scalp and hair surfaces to remove build-up such as dirt, oil, and other product residues while enabling lather.
Since sulfates are highly effective cleansers and can be great in many cases, some people may experience that they can remove natural oils from the hair and skin. With time, this can result in hair that feels dry, rough, or brittle. Shampoo’s without classical sulfates allow those that experience dryness from sulfates to wash the hair and scalp more regularly while maintaining shine.
