Anyone who suffers from dandruff caused by a fungal infection or skin conditions such as seborrheic dermatitis and pityriasis versicolor. Sometimes dandruff can also be caused by particularly strong hormone changes and fluctuations (menopause or puberty). Nizoral effectively combats the cause of dandruff and prevents it from reappearing. Nizoral can be used by adults and adolescents aged 12 or above.
