The condition of thin earwax is clinically called sugar thin ear, and it is mainly due to the different nature of the cerumen secreted by the cerumen glands in the external ear canal. This is not a disease. There are three common types of cerumen secreted by the cerumen glands in the external ear canal: first, the more common crumb-like, which can be handled by personal cleaning; second, cerumen that is more dilute and secreted more like this needs to be cleaned regularly at the hospital, otherwise it will block the external ear canal for a long time and lead to hearing loss; third, cerumen that is secreted by the cerumen glands in the external ear canal is harder. If the cerumen is hard, you need to use cerumen water to soften the hard cerumen before you can go to the hospital to clean it out. Otherwise, prolonged retention of cerumen may cause inflammation of the external ear canal in addition to affecting hearing.
