Are there health benefits to having a beard?

Some studies have shown that beards can harbor dangerous bacteria, while others have found beards beneficial in reducing skin cancer. So how do you determine whether you should let your facial hair grow? Dave Harvey, M.D., a dermatologist at Piedmont, gets to the root of the problem.

“The benefit of having a beard is protection, as well as esthetics,” Dr. Harvey says. “Its good protection against wind, chafing and traumatic injury. It's also a trend, so we see a lot of men with some form of facial hair.”

The health benefits of beards

Beards can:

Protect skin from sun damage. Beards can help protect the skin from harmful UV rays, though the degree of protection may depend on hair density and thickness. “You’re going to have some protection because hair is a reflective medium,” Dr. Harvey says. “Even though some UV rays get through, there is some scattering of light and that’s how it helps protect against sun damage.”
Keep you warm. Beards can add a layer of protection to your chin and neck, thus keeping you warm in colder weather. The longer and fuller the beard, the better it will insulate your face.
Make you feel more attractive. A study conducted by the Official Journal of the Human Behavior and Evolution Society found that men with moderately full beards are found most attractive, and men with full beards may be perceived as better fathers who could protect and invest in their children. “Men with beards have a powerful look,” Dr. Harvey says. “And that’s an attractive thing.”

Common problems for beard growers

Growing a beard is not always easy. If it is not properly cared for, it can become a harbinger of bacteria.

“If you don’t clean your beard well, and you let it just do its own thing, sometimes you can accumulate yeast and get dandruff within the beard,” Dr. Harvey says. “With that you’ll get a reactive scaling on the face and flaking like you would with dandruff. So those patients need to be put on antifungal shampoo.”

Beard growers also face the challenge of ingrown follicles that result in bumps known as acne keloidalis.

“Some men will get a raised scarring type of bump called an acne keloidalis of the neck,” he says. “So we offer them topical antibiotics or Retin A for those particular reasons.”

Tips for maintaining a healthy beard

It takes time, patience and dedication to grow a healthy beard. Try these grooming tips:

Let it grow. It can take at least one month to grow a beard. Put the razor back in your drawer and give your beard time to grow. “Be patient with the initial process,” Dr. Harvey says. “It’s not going to happen overnight.” If your facial hair looks a little unruly, try brushing it so that all the hair grows in the same direction.
Shampoo your beard. Wash your facial hair regularly. To prevent your beard from becoming dry and brittle, shampoo your beard with a gentle face wash or a moisturizing hair shampoo. You can also add olive oil or other natural oils to keep your beard soft.
Moisturize your face. It’s important to moisturize the skin beneath your beard. Without proper moisture, the body produces extra oil, which can cause breakouts.
Get some rest. “Often people who are stressed or don’t sleep well can have difficulty growing their beard,” Dr. Harvey says. “So I always recommend good rest.”
Eat right. A healthy diet ensures that hair follicles are properly nourished. Also, consider taking biotin, a vitamin that supports hair and nail growth.
Trim it up. Whether you want a full beard or a more angular look, get the right tools to shape it up. If you aren’t completely comfortable with clippers, check in with your barber for a more polished look.
