Pomegranate - Sweet and tangy, pomegranates pack a powerful punch of antioxidants called polyphenols, which protect the body’s cells from damaging free-radicals. They have also been heralded for their natural hair silkening properties, along with other dark fruit such as blackberries and cherries.  (Photo: Oli Scarff/Getty Images)

Avocado - Here’s another reason to dig into that yummy bowl of guacamole: avocados are rich in biotin, which keeps hair strands strong, as well as protein and heart-healthy fats. Try smoothing avocado oil on damp or dry strands as a conditioning treatment to seal-in moisture. (Photo: Michelle McMahon/Getty Images)

Walnuts - You’ve probably noshed on a handful of walnuts for a healthy mid-day snack, but these fiber-packed nuggets are also rich in omega-3 fatty acids, biotin and vitamin E. The combination is known to help protect hair cells from environmental damage from the sun, heat tools and other harsh conditions, as well serving as an all-natural shine-booster.

Bell Peppers - While there is no quick fix for growing your hair faster (hair grows only about one centimeter each month), consuming enough vitamin C, which your body uses to produce collagen and grow hair, in your diet can help keep the process on track. Toss some red bell peppers in your salad or snack on some oranges or strawberries, which are all rich in vitamin C. (Photo: DAVID HECKER/AFP/Getty Images)

Spinach - The green leafy vegetable has been called a superfood for good reason: it’s packed with iron, beta carotene, folateand vitamin C, which together help keep natural oils circulating throughout your scalp (a key function for healthy hair growth) and fight breakage. Try adding a handful to your morning smoothie or sauté some as a side dish for dinner to reap the daily benefits. (Photo: Justin Sullivan/Getty Images)

Sweet Potatoes - They’re already a staple on your fall and winter holiday menu, but now think of sweet potatoes as your secret for super soft locks. They are rich in beta carotene, which your body converts into vitamin A, a vital nutrient that helps regulate the natural oils in your scalp to fight dandruff and keep locks shiny. (Photo: PAUL J.

Poultry - Hair is composed of 97 percent protein, so look to add about two servings of healthy proteins like chicken, fish, lean red meats and legumes daily to help build strong strands. Poultry specifically has the added benefit of zinc, iron and vitamin B, which together help keep hair thick. (Photo: Cristina Cassinelli/FoodPix/Getty Images)

Water - While water is not technically a superfood, staying hydrated is essential for overall health, regulating everything from digestion to keeping your skin and scalp supple. If you’ve been battling hair dryness, try upping your intake of water to the recommended 3 liters for men and 2.2 liters daily for women. (Photo: Brian Hagiwara/Getty Images)
