Keratin is a protein that is naturally found in your hair, fingernails and skin. Brazilian keratin hair straightening treatments add additional keratin to your hair then use a heat source to flatten and straighten your hair so that it is stronger, bouncier and straighter.
Keratin treatments can last anywhere from a few weeks to a few months. But you may be able to extend the life of your keratin treatment and keep your hair looking lush, strong and straight longer by eating specific types of foods.
Protein is one of the most important building blocks your body uses to keep you strong and healthy. The body’s natural production of keratin relies on getting a steady stream of amino acids from the proteins in the foods you eat.
If your diet lacks adequate protein, it can affect keratin-rich tissues such as those found in your hair. People with protein deficiencies will often suffer hair loss or thinning hair.
Another important ingredient for keratin production is Vitamin A. This vitamin is important for regulating the growth of keratinocytes and helps activate keratin genes, which trigger keratin protein growth.
Lowe Vitamin A can cause keratin-rich cells to whither away. For example, people who don’t get enough Vitamin A in their diet can often get dead, dried out skin cells.
Vitamin D also regulates the growth and development of keratinocytes, as well as regulating their transition into corneocytes, which are the dead, keratin-rich cells found on the surface of the skin.
Adequate Vitamin D intake can help prevent psoriasis and other skin conditions.
Foods to Eat
Foods that are rich in protein, Vitamin A, and Vitamin D include dairy products like milk, yogurt and eggs.
Another rich source of protein and vitamins are nuts, legumes and lean meats. Green and orange vegetables — including pumpkin, sweet potatoes, and spinach — may also be good for your keratin hair treatment.
