Pay extra attention to your iron intake if you follow a vegan diet, since you rely solely on non-heme iron. Be aware that your body does not absorb non-heme iron as well as it does heme. Focus on plant-based foods with the highest iron content so that you can increase your ferritin levels. Broccoli, asparagus and dark leafy greens such as spinach, collards and kale are the richest iron sources among vegetables, while lima beans and kidney beans are iron-rich legumes.
Your hair grows out of your scalp, which is made of skin. Take care of your skin and you will encourage hair growth. Drink eight glasses (64 oz) of water every day. Eat biotin! You can get it naturally by eating nuts, brown rice, oats, and other foods (see box above.) Eat foods with essential fatty acids, including walnuts, salmon, and avocado. Give the collagen that wraps around your hair a boost by eating citrus, strawberries, and red peppers. Or take 250 mg of collagen daily.
