Please do not stick things in your ears, such as pencil tips, cotton swabs, or other objects. A boy can injure himself by doing so. Shampooing your hair can help keep your ears clean, but make sure they are squeaky clean after a bath or shower, and make certain to clean behind your ears. Earwax helps stop dirt from going down your ear canal. If you believe earwax is adversely affecting your hearing, tell your doctor, school nurse, or another adult you trust to see what can be done to remove some of the wax.
