Short-term treatment of dandruff with a combination of propylene glycol solution and shampoo.

Many studies now indicate an association between the lipophilic dimorphic yeast Pityrosporon ovale and dandruff. Propylene glycol has been proved effective in the treatment of pityriasis versicolor, Pityrosporon folliculitis, and seborrheic dermatitis. The patients in this study found treatment with a combination of propylene glycol, ethanol, and water, used with a shampoo, to be effective, easy to use, and cosmetically attractive. No side effects were observed by the patients.
