Tinea capitis, commonly known as scalp ringworm, is a fungal infection that affects the scalp and hair shafts. It is characterized by itchy, scaly patches that often lead to hair loss. Despite its name, no worms are involved. The term “ringworm” is derived from the ring-like appearance of the infection on the skin. Tinea capitis primarily affects children but can also occur in adults, particularly those with weakened immune systems.
