Many cases of tinea capitis are caused by contact infection, and most of the diseases are infected by animals. If we healthy people and people with tinea capitis are in close contact, especially head-to-head contact, it will be infected. And if there are animals at home, if animals have symptoms of tinea, contact with animals will also be contagious.

Extended data
matters need attention
1, it is necessary to control the frequency of hair washing. Generally speaking, it is most reasonable to control the frequency of hair washing between three and four times a week. Don't wash too much, because washing your hair too often will stimulate the scalp to secrete more oil, which will easily lead to more serious scalp problems.
2, pay attention to the method of washing hair, don't use your hands too hard to lick your scalp, especially for girls who still have nails on their hands, just gently lick your head, otherwise it is likely to hurt your scalp, so the phenomenon of dandruff will be more serious.
