Since last year’s presidential campaign, Obama’s gray hair has become significantly gray, is it genetic or stressful? Obama’s white head overnight. Two months ago just turned 47 years old, Obama has been in front of the public with a vibrant image, full of dark and thick hair is to make it look young and competent. But recently, when Obama appeared in the U.S. election public occasions, people were surprised to find that his hair from the previous deep black, suddenly turned gray, as if black hair full of “snowflakes”. The U.S. presidential election has come to the final stage of the sprint, when the mystery is about to be revealed, people began to comment on the new presidential candidate from the “head”. The N kinds of claims of premature gray hair At present, there is no conclusive medical reason for premature graying of hair, but the following three claims are more or less common. The first is the genetic theory. According to the data collected by scientists, congenital gray hair, as well as acquired gray hair in children and adolescents, often have a family history, that is, there will be more than one individual in the same family population with this gray hair trait. In China, premature graying of hair is characterized by family inheritance. If parents have premature graying of hair, their genes cause their children’s hair to be prematurely gray in nine out of ten cases. Researchers at the L’Oréal Hair Biology Research Center, on the other hand, have analyzed the causes of gray hair from a different perspective, namely the genetic theory they proposed four years ago. They believe that the reason why dark hair turns gray is a protein gene called TR-2 at work. Melanocytes determine the color of human hair. Cells containing this melanin are in the hair follicles of the scalp, drawing nutrients from blood vessels while making hair directly out of the scalp, and active melanocytes thus enter the hair, making it look black. Hair that turns gray is not because of the loss of melanocytes, but because the melanocytes that flow into the hair no longer have TRP-2 protein to help synthesize black, or have disappeared from the hair as we age. Therefore, the loss of the TRP-2 protein gene is the “culprit” for gray hair. In addition, many doctors believe that the cause of “gray hair” is complex, and is related to both genetic and physical factors, as well as acquired. And a variety of diseases disease attacks will often break the original balance of the human body, so that the endocrine disruption, prompting people to prematurely produce gray hair, such as typhoid, herpes, shingles, typhus, malaria and even influenza and other disease attacks will often make people prematurely appear gray hair. Obama worried about white head? Since there are so many claims of hair turning white, which one does Obama’s white head actually belong to? Obama’s hairdresser said, from 3 years ago Obama’s hair began to appear signs of gray hair, but apparently become gray from last year’s presidential campaign, even Obama himself has complained that “gray hair comes so fast”. ”Obama’s hair discoloration in a short period of time is likely to be caused by excessive stress.” The People’s Liberation Army’s 306th hospital dermatology attending physician summer Bao told the International Herald, intense election campaign, strong campaign pressure and the current financial crisis to politicians brought about by the negative impact is easy to make the body neurological dysfunction, so the secretion of melanin function will also be impaired, affecting the synthesis and delivery of pigment particles, gray hair will also grow very quickly. Therefore, mental factors are also one of the “black hair killers”. Xia Tianbao believes that, similar to Obama’s case, some young people have a lot of gray hair in a short period of time, and work stress, excessive anxiety, grief and other serious mental trauma or mental fatigue have a close relationship. As negative emotions such as extreme stress and sadness often cause a series of drastic changes in the body, resulting in serious endocrine disorders that cause people to develop gray hair in a very short period of time. “Wu Zixu crossed Zhaoguan overnight and worried his head white”, can be said to be a typical case of stress said. Healthy habits can prevent gray hair In the treatment and prevention of gray hair, Dr. Summer Paul suggests that you can try to start with a change in diet and lifestyle habits. The first thing to do is not to be partial to food and to consume more foods rich in vitamins and minerals, such as kelp, green vegetables and black sesame, and also to eat less artificially added foods, such as noodles, preserves or pickled products. You can also make your own black hair remedies to eat, such as taking fifty grams of He Shou Wu to water decoction and remove the slag, add a cup of white rice and the right amount of sugar, red dates, boiled into He Shou Wu porridge. Second, learn to relieve emotions, maintain a calm state of mind, relieve their own stress. Of course, it is also important to pay attention to good living habits to avoid diseases caused by bad habits that lead to early gray hair. For example, do not sleep with a wet head, because sleeping with a wet head is susceptible to wind and cold, leading to gray hair.
