The primary function of the shampoo and conditioner bars by The Sudsy Soapery Natural Products™ is to clean the hair! Our Shampoo Bars are a very gentle cleanser made of saponified fatty acids; the way people have been cleaning themselves for a few thousand years. There are other ingredients to help with moisture, tangles static etc., but nothing that will coat and prevent natural breathability of the hair. The ingredients in Sudsy Sopaery’s™ shampoo and conditioner bars are water soluble, meaning they wash of with water. No need to keep going back to harsh detergents just to keep the silicones from caking up your hair.
