What is a common sign of a fungal infection on the scalp?

A common sign of a fungal infection on the scalp is ringworm, which is not actually a worm but a fungal infection caused by dermatophytes. This condition can lead to noticeable symptoms such as itchy, red patches and hair loss in the infected areas, often characterized by a circular or ring-like appearance. The name 'ringworm' reflects this distinctive pattern.

While dryness, flaky scalp, and excessive oiliness can indicate other scalp conditions or dermatological issues, they are not specific indicators of a fungal infection. Instead, ringworm specifically suggests the presence of a fungal pathogen and requires attention for treatment. Therefore, recognizing ringworm as a sign of a fungal infection is crucial for proper diagnosis and intervention.
