Tinea capitis (ringworm of the scalp) is a fungal infection that affects the skin of the scalp, eyebrows, and eyelashes. The fungus responsible frequently attacks the hair shafts and follicles. Fungal hair infections are most common in children, and are characterized by mild scaling of the scalp (dandruff) or an inflamed bacterial abscess. If the infection progresses, children with tinea capitis usually develop patchy hair loss with some broken-off hairs that are visible just above the surface of the scalp. The patches of hair loss are usually round or oval, but sometimes they exhibit an irregular pattern. Medical treatment may be necessary, in combination with the regular use of an anti-dandruff shampoo and conditioner. Consult your doctor if your child has these symptoms in order to limit the severity of the infection and avoid permanent hair loss from occurring.
