Aside from age, genetics, and hormones, another factor that can lead to unhealthy hair is a major lack of nutrients and vitamins. Just like the rest of your body, your hair needs to eat healthily, and it's hungry for the right kinds of food. The hair needs right vitamins and nutrients supplied often to it and regularly for best growth and healthy development.

To really transform your locks in a revolutionary way, you need to stop eating foods that are bad for you. Instead, fill your pantry—and your stomach—with the following nourishing and wholesome foods:

1. Almond butter

Almond butter is one food that can be particularly good for your health as it is full of various nutrients such as protein, fats, and vitamins. It has vitamin E, which helps to make hair thicker and more lustrous. In a recent study, it was found that men who took vitamin E supplements daily experienced noticeable hair growth by up to 42 percent.

2. Tangerine

Tangerine has two important nutrients that benefit hair in big ways. It has vitamin C, which helps your body to better absorb iron from foods. Iron is important for optimal hair health. It is also rich in vitamin B12, which encourages hair growth while reducing hair loss. It is also instrumental in slowing down the graying process.

3. Spinach

Sometimes hair loss is caused by a lack of minerals in a person's diet. When planning what you eat, you want to make sure that you're not missing out on the important nutrients. Spinach is one food that rich in iron, and it also contains sebum, which is considered as the hair's natural conditioner. It is also rich in omega-3 acids, potassium, magnesium, and calcium.

4. Salmon

Salmon is a food that is a rich source of omega-3. It helps deal with symptoms of inflammation, which is another cause of hair loss. Aside from salmon, other fish sources of omega-3 are sardines and mackerel. Omega-3 helps your hair to be shiny and full and to grow well. It can also strengthen your immune system.

5. Eggs

Eggs are good for the hair because they are rich in biotin, which is a B vitamin that encourages hair growth and strengthens weak fingernails. Not having enough biotin in your body can lead to hair loss. You can also look to almonds, salmon, and avocados as good sources of biotin.

6. Liver

Liver may sound like a less appetizing food to you, but it is nutritious, not to mention delicious. It is also a rich source of iron, which can also be found in other foods like dark green leafy vegetables like spinach, lentils, and soybeans as well as in pasta and fortified grains. Your hair will thank you if you make these foods, especially liver, part of your diet.

7. Lean meat

It's a fact that if you don't get enough protein in your diet, your body loses muscle. This can also happen to your hair. Without sufficient protein, your hair can fall out at a greater than normal rate, and there will be less new hair to replace what was lost. Lean meat like chicken, fish, lean pork, and grass-fed beef are good sources of protein.

8. Sweet potatoes

Beta-carotene helps make your locks shiny and moisturized, and it also stimulates your scalp glands to produce sebum, your scalp's natural oils that give your locks their shine. This rejuvenating elixir can be found in rich-colored fruits and vegetables like sweet potatoes, carrots, and pumpkins.

If there are foods that are good for your body and for your hair, there are also foods that you should steer clear of as much as possible. The usual suspects are diet soda, sugar, alcohol, fast food, and starchy whites like bread, pastries, and cakes.

Aside from changing up your diet, there are other things you can do to improve the state of your hair.

Easing up on the heat styling and chemical treatments is one crucial, life-changing thing, as these can do great damage to your hair. But you don't need to sacrifice your style even without these, as you can wear extensions from Human Hair Extension Online instead. With extensions, you can look good and switch styles without damaging your locks.
