Oysters are an excellent source of zinc and protein. When consumed regularly, they help prevent dry, flaky scalp, fight DNA damage, and boost hair shine. The iron in oysters protects against anemia, one of the main causes of hair loss.
Pumpkin seeds are a favorite protein source for vegans and vegetarians. These tiny seeds pack large amounts of vitamin A, vitamin K, zinc, and omega-3s, leading to fuller, stronger hair.
Make sure your diet includes hemp seeds, which are about 30 percent protein by weight. Loaded with healthy fats, they moisturize the scalp and hair, prevent breakage, and enhance hair growth. Eating just one or two tablespoons a day can make your locks shinier and fuller. Add hemp seeds to smoothies, sprinkle them over salad, or make a delicious trail mix at home.
