Dandruff and seborrhoeic dermatitis are associated with increased numbers of a type of fungus (yeast) called Pityrosporum. This occurs naturally on everyone's skin, however, people with dandruff and seborrhoeic dermatitis seem to have more Pityrisporum than usual. Tinea versicolor (otherwise known as pityriasis versicolor), a condition, which causes white to brown patches to develop on parts of the body, is also associated with Pityrosporum. Nizoral shampoo is one of a group of products called anti fungal, which are used to treat such conditions and work by destroying the fungus. Nizoral shampoo is available to the pharmacist as bottles containing 120 ml.
