The Trappistines of the Abbey of Our Lady of Nazareth in Brecht (Belgium) came up with a world premiere shampoo to which 10% of the renowned Westmalle Dubbel was added. It is the first hair care product made with a real Trappist beer. The Meurice Institute in Brussels did a scientifically based study about the benefits of beer for skin and hair. The study showed that there are many advantages, thanks to the polyphenols, trace elements, vitamins and minerals in the beer. They stimulate the natural volume of the hair and make it shiny.
