Tinea capitis is a fungal infection that occurs on the scalp and hair. Ringworm is the common name for a fungal infection, and tinea capitis, a fungal infection that occurs on the head, is more common in children and less common in adults. Depending on the specific genus of the fungus, there are four types of ringworm: ringworm yellow, ringworm white, ringworm black spot, and ringworm pustulosis. Symptoms vary and are mainly red to yellowish-red spots, inflammatory papules, hair that breaks easily, or pus-like manifestations. The diagnosis can be confirmed by hair fungal microscopy. Treatment is not very different, mainly five key steps “serving, cutting, washing, rubbing, eliminating”, one cannot be missing. That is, oral antifungal drugs, cut short hair, insist on daily shampooing with antifungal water, rubbing antifungal cream or salve, disinfecting clothing, bedding, household items, etc., the course of treatment is about two months. If the course of treatment is insufficient, it is easy to repeat. Commonly used drugs include itraconazole oral solution, ketoconazole lotion, butenafine cream, 2% iodine tincture, etc. If bacterial infections are combined, antibacterial treatment should be added, and incision and drainage are strictly prohibited when there is pus. Tinea capitis is most common in children, especially in families with dogs and cats, and is easily confused with plucking fetish and scalp furunculosis, which may lead to scarring alopecia and affect future beauty if treatment is delayed.
