Some cases of tinea capitis can heal on their own. Clinically, tinea capitis is divided into white piedra, black dot tinea, yellow piedra, and kerion. White piedra can heal on its own, usually after puberty. Post-puberty, Malassezia may colonize the scalp and secrete free fatty acids, which have a certain killing effect on white piedra, so it may resolve without treatment. However, if the tinea capitis is yellow piedra, black dot tinea, or kerion, these types cannot heal on their own and may cause permanent hair loss. Therefore, it is crucial to treat these types promptly with antifungal medications under a doctor's guidance and pay attention to personal hygiene.
