What kind of skin problems is a Ketoconazole 2% w/w Soap used to treat?

This soap is an antifungal wash mainly used for fungal skin infections, things like ringworm or itchy, scaly patches from fungal overgrowth, and it can also help with dandruff-related scalp and skin issues. It works well for these specific conditions, but not every skin problem is fungal in nature, so if things don't improve or you're not sure what's causing it, having a doctor take a look will get you the right treatment from the start.
