You’ve probably thought a lot about what your beard conveys about your personality (and if not, here’s a handy explainer from an actual beard scholar that will tell you exactly what it says), but have you ever thought about what it says about your health? Turns out, your beard is crying out to be heard. Here, Joel Schlessinger, MD, a Nebraska-based board-certified dermatologist and RealSelf advisor, and Paul Salter, RD, and nutrition editor at, explain what your beard is trying to tell you.

If your beard is: Falling out in small, round patches


You may have alopecia barbae, an autoimmune disorder that causes your body to start viewing your hair follicles as “intruders” and attack them until hair stops growing, Dr. Schlessinger explains. The good news is that it’s not contagious or dangerous in any way. The bad news is that it can cause irritation, burning, and inflammation. While there’s no real cure, it is treatable. Dr. Schlessinger says that minoxidil (Rogaine), has been shown to treat alopecia barbae; however, it’s not currently FDA-approved for use on the face, so talk to your doctor before starting any kind of treatment. Additionally, if you notice that your facial hair loss is accompanied by hair loss on your scalp, fatigue, weight gain or loss, or changes in your sleeping habits, mood, energy level, or digestion, see your doctor immediately, as it’s possible that you could have a thyroid disorder, lupus, or diabetes.

There are a number of possible causes, including a potential nutritional deficiency. “Chronic malnutrition has a major impact on hair loss and growth,” Salter says. “If adequate calories aren’t consumed, hair growth and maintenance won’t be optimized.” Protein in particular plays an integral role in the building and repairing of tissues, so your body will pull protein from wherever sources it can if you don’t get enough protein, which can lead to hair loss. Stock up on healthy sources of protein such as eggs, lean beef, chicken, turkey breast, and Greek yogurt. Other nutrients that encourage healthy hair growth include vitamins E and C, zinc, biotin, and fatty acids, so making sure you eat a well-rounded diet and drink plenty of water; both are key to healthy hair growth. You may also have a food allergy, which can cause a large-scale production of inflammation in your body. While symptoms vary from person to person, hair loss is very common, Salter says. Hair loss is also a common symptom of anemia. Keep in mind that facial hair differs in structure from scalp hair, and Salter cautions that he’s not aware of any research that focuses on how nutrition interventions specifically impact facial hair growth. Bottom line? If you notice any hair loss either on your scalp or face—especially if it’s accompanied by other symptoms—talk to your doctor.
