I like to know does it matter what brand of ketoconazole shampoo one uses? Being in North America, is Nizoral (brand name) the one that I should buy? Is it 2% or 1% (both are available as non-prescription)? I also see that there are numerous other brands available with ketoconazole that are far more expensive because they have other ingredients. Does it matter?
I am very confused...
