A
Healthy, shiny hair is an attainable goal for many people. What you eat can bring luster and strength back to your hair. A balanced diet filled with so-called superfoods like certain fruits and oils treat your hair from the inside out.
Oils
The omega-3 fatty acids in eggs, walnuts, and fatty fish like salmon help make hair shiny. These oils can also be obtained through some vegetable oils or flaxseed oil, but are found in higher amounts in oily fish and eggs. The protein in these foods also helps hair grow strong and healthy. Also found in eggs are B12 and biotin, both of which are essential for healthy skin, nails, and hair.
Avocado
Avocados contain high amounts of vitamin E. Only 2 ounce of a medium-size avocado contains 8 percent of your daily recommended intake of vitamin E. If you don’t like to actually eat avocado, you can make an avocado mask to put on your hair. Vitamin E helps to keep your hair color bright and prevents split ends.
Coconut Oil
The medium-chain fatty acids in coconut oil are used differently by your body than other saturated fats. An added benefit of coconut oil is its ability to make your hair shiny and healthy. Use coconut oil to cook your chicken or seafood, add it to your salad, or put it directly on your hair as a mask. Coconut oil’s anti-fungal agents also help protect against and treat dandruff and other scalp problems.
Vitamin C Fruits
Fruits high in vitamin C
such as oranges, peaches, pineapples, strawberries, and kiwi - help maintain healthy hair and fight against free-radical damage from the environment to protect your hair against pollutants. Make sure to eat lots of fruits high in vitamin C. You can also apply the juices of these fruits directly to your hair by mixing it into your shampoo.
