According to a scientific study published in Biotechnology Reports recommends increasing the proportion of protein in food.
Protein is an essential part of food for hair
“Your hair is made up of protein filaments called keratinwhich makes protein an element essential of your food for the hair”, reports Dr. Sandy Skotnicki, dermatologist, to our English colleagues from Express.
As part of the study, a type of keratin was applied to the hair to see if it might repair human hair.
“K31, a type I acid keratin, is a major protein in the keratin complex of human hair and is essential for maintaining the tensile strength of hair. The refolded and partially purified K31 protein, when applied on damaged hair chemically increased hair diameter by up to 49%. There résistance mechanics of bleached hair has almost double following a single treatment of K31,” the researchers describe.
“The application of K31 resulted in marked improvements in smoothnessof diameter and the mechanical resistance of damaged hair”.
In addition to proteins, bet on certain vitamins can improve hair health. Nutrients such as vitamins and minerals can play a crucial role in maintaining a good level of hair density, such as zinc, vitamins C, E and biotin, which is a form of vitamin B7 often lacking in hair. people prone to hair loss.
