"Prescription" Nizoral-cheaper?
A guy I know from Hong Kong has a bottle of Nizoral (anti-dandruff shampoo) he got prescribed to him over there. He needs a new bottle and we were wondering; is the "prescription" Nizoral the same thing that you can buy over-the-counter here, or is his version stronger? Is there a "prescription" Nizoral under the same brand that's stronger (kinda like Tylonol-3)?
