Vitamins and Supplements for Your Hair 1

Protein

More than 90 percent of your hair is made up of protein, so you need to have enough protein in your diet to support hair growth. Fortunately, most people in the United States get plenty of protein naturally from their diet. Foods such as meat, poultry, fish, eggs, and dairy products are high in protein. Vegetarians can get protein from plant sources such as soybeans, seeds, and nuts.
