Ringworm is a fungus, and ringworm is also known as a fungal infection of the head. Ringworm may cause hair loss, causing significant localized flaking, as well as itching and infection, so once ringworm occurs it should be treated promptly. The first thing you need to deal with is to keep the habit of cutting your hair, and if you are not thinking about aesthetics, it is best to cut it all off or cut it as short as possible for about two months. You should also wash your hair regularly with sulfur soap or ketoconazole lotion because fungal infections must be removed as much as possible by washing your hair to remove the fungus on the surface and the skin flaking caused by it. The medication is mainly antifungal drugs, such as ketoconazole, terbinafine, and bifenbendazole cream, etc. If it is serious, you can also consider oral itraconazole, fluconazole, and other drugs, which are all antifungal oral drugs, and only comprehensive treatment can cure dermatophytosis as much as possible.
