You've probably heard about a clay mask for your face before. But have you heard about the benefits for using clay on your hair? Is clay the new all natural shampoo? Simply put, Clay is aged volcanic ash or powder. Although Bentonite clay is widely used, it is not the only known clay on the market. Montmorillonite clay is another clay powder that can be used on the hair. It is named after a region of France called Mont Morillon, where the clay was first discovered. Bentoinite clay, on the other hand, was found in Benton, Wyoming. Bentonite, therefore, became its trade name. Clay contains Silica, Calcium, Magnesium, Potassium, Iron, Sodium, and Copper. Clay can be ingested or applied topically. It absorbs impurities and removes toxins from the hair.
