Answer: you can use anything that you find on the store shelves for athletes foot fungus. Ringworm is a fungus. I don't remember what the active ingredient it. But they all list ringworm on the back. Now, if the ringworm is on the scalp, it takes a whole different kind of medicine, it is oral and has to be prescribed by the doctor. The meds used on regular ringworms and ringworms on the scalp are totally different, a ringworm on the scalp will not go away with a topical cream.
