How often do you clean your hair dryer? It's a good idea to keep your blowdryer pristine for your own safety as well as the enjoyment of family and friends. A well-oiled machine will keep your hair looking and smelling fresh for a long time to come, so you'll want to make sure it gets regular dusting and vacuuming attention. You'll also want to look for a reputable manufacturer that can stand up to the wear and tear of frequent use. This is especially true if you're planning on having the appliance in your bathroom for the foreseeable future.
