Like the rest of the hair on your head, facial hair needs to be washed regularly or it will quickly come to look like the fur of a dead animal. "Most guys do just fine using a gentle face wash like Dove MenPlus Care Face Wash or even regular hair shampoo," says Dr. Peterkin. "But it's very important to fully rinse off any soap residue to avoid drying and flaking."

For beards that are especially wiry and unruly you might consider using beard oil or balm. They help weigh down any flyaway whiskers and seal moisture into the hair, making it appear shiny and healthy, and feel soft instead of bristly.
