What is the common name for tinea capitis?

Tinea capitis is a fungal infection that primarily affects the scalp. The common name for this condition is "ringworm of the scalp" due to the circular, ring-like patterns that can appear on the scalp, resembling a worm-like infestation, even though it is caused by a fungus and not an actual worm.

This condition typically manifests with symptoms such as itching, flaking, and hair loss in the affected areas, making it important to recognize and treat promptly. The name "ringworm" highlights the characteristic appearance of the rash and can be misleading as it suggests a parasitic infection. However, understanding this terminology is crucial for proper diagnosis and treatment in a barbering context, as it can affect clients' scalp health and hair.

The other options refer to different scalp or hair conditions. Scalp psoriasis is an autoimmune disorder causing red, flaky patches; alopecia universalis is a form of hair loss that affects hair on the body; and dandruff is a non-fungal condition characterized by the shedding of dead skin cells from the scalp. None of these conditions are caused by a fungal infection like tinea capitis is.
