Your doctor can often make a diagnosis of ringworm or another condition affecting the scalp based on a visual examination of the scalp and your answers to questions.
If the diagnosis is uncertain, your doctor may take a sample — hairs, a swab from the scalp or hair, or a scraping of scaly skin — for examination under a microscope, which can reveal the presence of fungi.
