In brief: Quite a while

Compared to many other infections these are a longer investment of time and effort.
The germ has gone deep into the hair follicles and require oral medication to reach/eliminate. Difficult cases can take a month or more of medication for final cure. Topical medications can sometimes provide a cosmetic benefit at the level of exposed skin, but won't cure it alone.

In brief: 2-3 weeks

Treatment for ringworm can take two to three weeks to show significant improvement.
Any associated hair loss can take longer to grow back.
