There are many ear hairs mainly for the following reasons: 1. In the newborn period, there are more ear hairs, mainly because there are more ear hairs, which mainly play a protective role and can protect the tympanic membrane from flying insects outside the ears and secretions that enter the tympanic chamber. 2. If the father is hirsute, the child will be hirsute if he is a boy, but girls do not inherit. Hirsutism is not a disease, it is genetically related and has a protective effect on the patient. If the patient feels that there is too much hair in the ear, it can be trimmed locally, but not too much so that outside flying insects and foreign objects can easily enter the eardrum and damage the patient’s ear.
