What are some tinea versicolor, natural treatments?

Wrong question. Cyanide is "natural". So is poison ivy. What you need to know is what is effective & what is safe. Otc you can get Miconazole or Clotrimazole cream: cheap, safe, effective. You can also get head& shoulders or selsun or ketoconazole shampoo. Rub on the shampoo 1 or 2 hours before you get in the shower. Prescription azole tabs are the easiest treatment.
