Benefits of gray hair

A team of scientists from University College London, analyzed the genomes of 6,300 residents of Brazil, Colombia, Chile, Mexico and Peru, has identified a gene involved in IRF4 appearance of gray hair.

The main function of irf4 - participate in the regulation of synthesis of melanin, the pigment responsible for hair color, skin, iris, for the appearance of freckles. If there is a variation in the genome gene IRF4 graying may occur at an earlier age.

However, as noted by the research team led by André Ruiz-Linares, graying hair is not only associated only with changes in the genome, it can also occur as a result of stress, illness, lack of vitamins and minerals, poor lifestyle choices.

According to scientists, people spend too much time and money to repaint the gray hair back to its natural color. Revealing a more precise mechanism of formation of gray hair, the researchers say, will help them to develop not only new methods of prevention of gray hair, but also the treatment, the possibility to pay back the graying.

Andre Ruiz-Linares, studying the genetic component bloom, also found that the variation IRF4 gene responsible for an earlier occurrence of gray hair, the most rare among the indigenous population in Latin America than in people whose ancestors were Europeans.

In the study, in addition IRF4 scientists have found genes that are responsible for other properties of the hair: curly, eyebrow thickness, thickness of hair covering the face.

The authors stressed that their work is unique. They intend to continue to study the aging process.

If you touched the problem of early gray hair, do not despair. Remember that many go to face the silver hair color, highlights their personality and bright eyes. How to write some stylists, well-groomed hair streaked with gray, giving the image of consistency and reliability, look stylish and attractive.
