Tinea capitis is a fungal infection of the scalp or hair follicles caused by dermatophytes. There are several types of tinea capitis. If it is white piedra, it appears as scattered, spot-like scaly patches; if it presents as kerion, significant inflammation will occur with many small pustules forming on the scalp; if it is yellow piedra, scalp scales will appear. Regardless of the type of tinea capitis, it is crucial to treat it promptly to prevent spreading.
