The common pathogens in China are Trichophyton schlegeli, Microsporum ferrugineum, Microsporum canis, Trichophyton purpureum and Trichophyton ampullatum.

Second: tinea capitis mainly transmitted by direct or indirect contact with patients or sick animals, especially when the scalp is more easily infected by trauma such as shaving, so hairdressing is one of the ways of transmission. However, fungal infection may not always cause tinea capitis, which is closely related to the body's resistance to fungi. Most adults have strong resistance to fungi, but children are weak, so tinea capitis is more common in children.

At the beginning, it is red papule or small blister, followed by the formation of scales, and then gradually expands into ring damage with clear boundary around. Papule and blister can be seen at the edge, and there is no exudate on the surface.
