I like eating nuts as a healthy snack because I know that they are high in good fats, vitamin E and fiber. Nuts can also help prevent hair loss! Try eating some walnuts, peanuts and almonds as your afternoon snack. You can also make a trail mix using these nuts. Walnuts, peanuts and almonds contain zinc and omega-3s, both of which are widely known for reducing the shedding of hair and promoting healthy hair!
