Hair loss reason: You’re not eating enough protein
Another reason to load up on protein at every meal: It helps create your hair. A lack of protein causes your hair to stop growing, fall out, and even change color, according to the Institute of Medicine. Women should be getting at least 46 grams of protein per day. Neva Cochran, a registered dietitian in Dallas, Texas recommends that your protein intake comes from a variety of food sources, not just meat. Adding half a cup of pinto beans to your next dinner gets you an extra 11 grams of protein.
Hair loss reason: You’re not getting enough iron
For vegetarians, or people trying to limit their meat intake, becoming iron deficient is a real concern, and a diet lacking in iron may lead to hair loss. Women between the ages of 19 and 50 should get 18 mg of iron per day, and women 51 and older should get 8 mg per day. But don’t run to the drugstore for supplements so quickly: Cochran does not recommend taking an iron supplement without having a proven iron deficiency and consulting with a doctor. Instead, add iron-rich foods to your diet. These foods include clams, soybeans, squash, lentils, and spinach.
Hair loss reason: You’re coping with a high-stress situation
Feeling anxiety about your performance review or your annual doctor visit is unlikely to cause chunks of your hair to fall out. But intensely stressful situations—think: life-threatening medical diagnosis, death of a loved one—can trigger hair loss even weeks after the initial event. This hair loss does not have to be permanent. Your hair can grow back if you learn to control your stress, according to the Mayo Clinic. Here’s how to keep calm and tackle stress effectively.
