The reason for President Obama's hairlessness after 8 years as President of the United States

Scientists believe Obama's hair is much worse after eight years at the White House not because of work pressure but genetics.

In 2011, when asked by a reporter why the hair was so much gray, US President Barack Obama said his hair was grayed out by the gene, not by work pressure.

"My grandfather's hair was silver when he was 29, so I guess I do too. This coincides with my term as president," Mr. Obama said.

According to Live Science, biologists say Obama's explanation is absolutely correct.Genetics is the dominant factor in the process of hair loss and Mr. Obama is a typical case. According to the study, the starting age of silver hairs of European-American white people is 35, Asians are nearly 40, while Africans are about 45. Obama has a white mother and his father is African, so It was understandable that his hair began to fade when he was 40 years old.

Scientists disagree with the idea that Mr. Obama's hair is suffering from stress with work pressure.

"Look at the hair of the Egyptian or Libyan youth, or the young Israeli soldiers. Their hair is not at all in spite of being in danger every day, extreme stress," said Gerald Weissmann, editor-in-chief. FASEB magazine specializes in biotechnology, said. "That's a gene, only a gene."

However, not all scientists agree with Weissmann's judgment. Andrzej Slominski, a dermatologist at the University of Tennessee Medical Center, said in addition to the genetic factor, there is "solid evidence" that environmental factors such as stress also cause hair loss.

"Stress and silver hair are related to each other. This phenomenon has been described in World War II, when soldiers suddenly turned their hair quickly, even white in one night , " Slomonski said. However, he added "this mechanism is not clear".

Ralf Paus, an expert at Luebeck University in Germany, said that psychological stress can increase the production of free radicals and damage to melanin - pigment cells that determine the color of hair follicles, leading to phenomena. gray hair.
