Purdruff is more than just a shampoo. It combines the anti-fungal properties of Piroctone olamine with the natural goodness of 7 botanicals like Saponaria officinalis (common soapwort), Citrus limon (lemon), Nasturtium officinale (watercress), Salvia officinalis (sage), Hedera helix (ivy), Arctium majus, and Fucus vesiculosus (seaweed). Purdruff not only helps to fight allergic conditions at the very root but also soothes, refreshes and heals the skin. Purdruff has been proven to effectively fight against dandruff.
