    Salmon for Shine

    Fish like salmon, sardines, and mackerel are packed with healthy omega-3 fatty acids. Your body can't make these healthy fats, so you have to get them from food or supplements. They help protect you from disease, but your body also needs them to grow hair and keep it shiny and full.

    Grow With Greek Yogurt

    It’s packed with protein, the building block of your locks. Greek yogurt also has an ingredient that helps with blood flow to your scalp and hair growth. It’s called vitamin B5 (known as pantothenic acid) and may even help against hair thinning and loss. You may recognize pantothenic acid as an ingredient on your hair and skincare product labels.

    Spinach to Battle Brittle Hair

    Like so many dark green leafy vegetables, spinach is full of amazing nutrients. It has tons of vitamin A, plus iron, beta carotene, folate, and vitamin C. These work together for a healthy scalp and mane. They keep your hair moisturized so it doesn't break. Want to mix it up a little? Kale is another great green choice.

    Guava to Prevent Breakage

    This tropical fruit brims with vitamin C. It protects your hair from breaking. One cup of guava has 377 milligrams of vitamin C. That's more than four times the minimum daily recommended amount. Bonus!

    Iron-Fortified Cereal to Prevent Loss

    Getting too little iron can lead to hair loss. But you can find this important nutrient in fortified cereal, grains, and pastas, and in soybeans and lentils. Beef, especially organ meats like liver, have lots of it. Shellfish and dark leafy greens do too.

    Lean Poultry for Thickness

    When you don't get enough protein, hair growth "rests." Since it stops and older hairs fall out, you can have hair loss. To get protein from meat, pick lean options like chicken or turkey, which have less saturated fat than sources like beef and pork.

    Sweet Potatoes to Fight Dull Locks

    Have dry hair that's lost its shine? Sweet potatoes are filled with a good-for-you antioxidant called beta carotene. Your body turns beta carotene into vitamin A. That helps protect against dry, dull hair. It also encourages the glands in your scalp to make an oily fluid called sebum that keeps hair from drying out. You can also find beta carotene in other orange vegetables like carrots, pumpkin, cantaloupe, and mangoes.

    Cinnamon for Circulation

    Sprinkle this spice on your oatmeal, toast, and in your coffee. It helps with blood flow, also called circulation. That's what brings oxygen and nutrients to your hair follicles.

    Eggs for Growth

    Your protein and iron bases are covered when you eat eggs. They're rich in a B vitamin called biotin that helps hair grow. Not having enough of this vitamin can lead to hair loss. Biotin also helps strengthen brittle fingernails.

    Oysters for Fullness

    These are rich in zinc. When you don't have enough of this mineral in your diet, you can have hair loss -- even in your eyelashes. Cells that build hair rely on zinc to help them work their hardest. You can also find this mineral in beef, crab, lobster, and fortified cereal.
