Stress Make Obama quickly gray hair?

There is a change in the appearance of the number one in the United States, President Barack Obama. Her hair looks more gray. When asked by the media, he said that the change was influenced by genes, not because of job stress.

"My grandfather started graying when he was 29 years old. So a matter of time when it happened to me. Incidentally this hair color changes during my tenure as president," he said as quoted by ABC News.

Obama's answer may seem diplomatic. But biologically, gray hair that comes more quickly indeed heavily influenced by heredity, especially at the age of Obama, who had stepped 50 years. At that age, 50 percent of men will experience perubanan in most of their hair.

In an article published in the Journal of Investigative Dermatology in 2005 reported that Caucasian hair graying average of 30 years in middle age, while Asians at the end of the age of 30 years, and Africans in the mid 40 years. Obama, whose mother is Caucasian and his father's bloody Africa, began to show changes in hair color at the end of the age of 40 years.

Regarding the influence of stress on the hair color change, it turns out the experts disagree. Scientific proof that stress makes people go gray also not convincing.

According to biologist Gerald Weissmann, editor senior biology FASEB journal, until now there is no literature that says that stress makes your hair gray faster.

"Look at the hair of young people in conflict areas or army soldiers who fought. Their hair was not gray though chastened every day stress. Even more gray hair was instrumental in bringing about the gene," he said.

However, not everyone agrees with the conclusions Weissmann. According to Andrzej Slominski, a dermatologist, genetic indeed a big influence on the onset of gray hair, but there is scientific evidence which states that environmental factors like stress also influential.

"There is a link between stress and gray hair. This phenomenon has never appeared when World War II when the hair of the soldiers suddenly became visible gray," he said.

Meanwhile, according to other experts, the impact of stress on the hair may occur because of stress hormones that will trigger the production of free radicals. This causes damage to the hair pigment.

In addition, stress also affects the body, such as suppress the immune system, cause digestive disturbances, and increased blood pressure. Experts say, the change process also affects the hair follicles.

Although the primary cause of the appearance of gray hair at a young age is not known with certainty, the basic theory remains the same occurrence of gray hair. It happens because hair follicles begin to ripen and gradually lose the pigment cells that give color to the hair. When the hair had been black or another color loss, replacement more often white or gray hair.

Hair that is colored white or gray is actually still the same with your hair that long, but now no longer have a color. At first glance it looks gray hair because it contrasts with others that are still colored hair.
