What is tinea capitis commonly known as?

Tinea capitis is commonly known as ringworm of the scalp. This fungal infection affects the scalp, causing redness, itchiness, and sometimes hair loss. The term "ringworm" stems from the appearance of the infection, which can resemble a circular ring on the skin. Tinea capitis is caused by various fungi that thrive in warm, moist environments, and it is contagious, often spreading through direct contact or contaminated items like combs or hats.

The other options refer to different conditions. Barber's itch, for example, refers to a bacterial infection often seen in men that affects the beard area. Scalp psoriasis is a skin condition characterized by red, flaky patches on the scalp due to an immune-mediated process. Hair follicle infections occur when hair follicles become inflamed, typically due to bacteria or fungus, but are not specifically related to the ring-like appearance associated with tinea capitis. Understanding these distinctions helps clarify why tinea capitis is accurately referred to as ringworm of the scalp.
