How fast can I make my ringworm on the scalp go away?

Fungus of scalp. A ring worm, is in fact, not a worm, but a microscopic germ called a fungus. Most scalp ringworms occur in children, and if you are an adult, it is likely that what you have is not really s ring worm, or fungus, but something else. It is very hard to get rid of scalp ring worm without an internal medicine, and I suggest you go to a dermatologist for a proper diagnosis, and good treatment.
Depends. How quickly a scalp ringworm resolves depends on how extensive it is, how it is treated, and whether it has caused hair loss. Two to three weeks is a reasonable estimate for an "average" case of scalp ringworm, plus the time it takes any hair that has fallen out to grow back.
