Photos of President Donald Trump deplaning from Air Force One on Friday sparked questions online after his hair appeared a noticeably darker shade of brown — a departure from his signature blond. It’s the second time in a month his hair has drawn scrutiny. In early August, he faced speculation that he may have been wearing a wig while giving a speech on economic policy in Las Vegas. For the recent photos, hair loss specialist Dina Kales and wig specialist Andrew Disimone told HuffPost that it was very clear the president had simply dyed his hair. “A darker hair color shade was used to color his hair,” Kales, who owns The Top Shoppe in New York City, said. “Since the roots are completely white, and his ends have some previous dye on them, the already colored hair has taken a darker hue, in comparison to the roots, which have been colored but seem to be a lighter shade.”JIM WATSON via Getty ImagesDonald Trump stepped off Air Force One in Morristown, New Jersey on Sept. 4 with a noticeably darker hair color. In the past, the president’s hair looked like it was being worked with an ash-based blond dye, which is why it sometimes gets a purple hue in photos, Disimone said. “In my opinion, he switched his base color to either a neutral or an ash tone, and it’s just depositing into his gray hair,” Disimone said. “That’s what I see going on, and he definitely changed his hair color.”But Disimone says he can tell it’s just a new dye because the president’s scalp is still white and lighter than the rest of his face, which it usually is because of his spray tans.The hair perimeter is also why Kales feels confident that this is the president’s natural hair. “Many wigs are denser than natural hair, which makes getting a seamless blend more challenging and a giveaway to someone with experience,” she said. “The hairline is also a critical telltale of a wig; they do tend to be thick, without much recession, and somewhat bulky-looking. Trump has been photographed numerous times windblown with his hairline completely exposed. Based on those [recent] images, I stand by my opinion that his hair is natural and not enhanced with a wig.” Trump biographer Michael Wolff told The Daily Beast’s “Inside Trump’s Head” podcast over the weekend that the president’s team carries a portable kit to fix Trump’s hair, which includes patches of different colors that are then applied with “some kind of paste,” according to Wolff. “He has somebody who’s following, and there have been a couple of people over — certainly over the political years — who’ve carried the patch kit,” Wolff said. “They are next to the people who carry the nuclear codes.”Wolff did not specify who currently carries the kit. HuffPost reached out for further comment on the podcast remarks but did not hear back as of reporting. “The maintenance of this hair is a major enterprise and has been for many years,” he said on the podcast.

First President George Washington, whose ponytail alone can be identified, significantly stood out during his term since a full head of hair was considered a sign of strength at the time. Theodore Pappas, the author of “Combing Through the White House: Hair and Its Shocking Impact on the Politics, Private Lives, and Legacies of the Presidents,” told HuffPost that hair has always played a role in presidencies for centuries. “Asking for a snippet of a president’s hair was a common way of honoring presidents in the 18th and 19th centuries — it was equivalent to asking a celebrity for a selfie today,” he said. “Washington even took time out from the Revolutionary War while at his hellish camp at Valley Forge, where thousands of his troops died, to mail a sample of his hair to an admirer. So, although Trump’s hair is certainly a novelty, this obsession with presidential hair is historically nothing new.”President Abraham Lincoln was mocked by the press for his hair since photos were becoming more common in the 1860s, and President William H. Taft was viewed as unclean for having a mustache. (Pappas noted that the U.S. has not had a significant political leader with a mustache or thick facial hair since Taft left office in 1913 — up until Vice President JD Vance.) Meanwhile, former President John F. Kennedy was repeatedly praised for his hair and appearance, Pappas said. “Hair can ‘shed’ great light on the presidency — it’s not a trivial lens for gleaning insights into the presidency and the country at large,” Pappas said. “From Washington to Trump, presidential hair has always been a lightning rod for commentary.”
