Removal of wax layer too often will raise incidence of ear infection

The removal of wax layer too often will raise incidence of ear infection because the wax layer, produced from sebaceous and ceruminous gland of ear pinna, keeps the ear canal well lubricated and prevents any dust particles rom entering into the ear canal. Hence, removal of the wax layer often will increase the chance and amount of dust particles entering into the ear canal thereby raising the incidence of ear infection.
