Having a keratin hair treatment by Marcia Teixeira adds keratin — a natural protein already found in your hair, skin, and nails — to make your hair look long, straight and luxurious.

But there also are certain foods you can eat that can improve the look, strength, and body of your hair. If you want your hair to look and feel its best, all you need to do is include some of these foods into your everyday diet.

Keratin Hair Treatment — Proteins That Can Make Your Hair Glow

Your hair is composed mostly of protein cells. So increasing the amount of protein in your diet can help your body replenish the protein in your hair so that it looks smoother, fuller, and lusher.

Foods that are high in protein include chicken, turkey, fish, and dairy products, especially eggs. If you don’t eat meat, you can increase your protein intake by eating more legumes such as beans, as well as nuts.

Keratin Hair Treatment — Making Your Hair Stronger with Iron

Iron is one of the most important nutrients for your hair. People suffering from hair loss frequently also have an iron deficiency.

Both your hair follicles and their roots are fed by your blood, which is rich in iron. So when your iron levels are lower, a condition known as anemia can occur.

Anemia can disrupt the supply of nutrients to your hair follicles, negatively impacting hair growth. The result can be hair shedding and the development of bald spots.

Fortunately, adding iron to your diet is easy. Simply increase foods like red meat, chicken and fish, all of which are high in iron. If you don’t eat meat, try adding more spinach and other leafy green vegetables like kale, broccoli, and lettuce to your diet.

You really are what you eat. Add foods that can make your hair stronger and more full is not only easy, it’s also delicious!
