The main ingredients are natural Origanum (oil from the oregano plant, or Origanum vulgare), and natural menthol, most commonly made from the cornmint plant (Mentha arvensis). These ingredients work together. Grapeseed oil gives the product better handling characteristics. The Shampoo contains surfacants (soap-like ingredients), thickeners, and the like, just like any other shampoo.
It’s actually a little more complicated than that. The Origanum we use is of a special kind. It’s expensive and is not always available. We constantly monitor the quality of this ingredient to make sure it complies 100% with our specifications. Also, we use only pure (USP grade) natural menthol. It comes as large, clear crystals. Synthetic menthol will not do; only levo- menthol will work.
