Photos: Trump Admits He Is Going Bald
Donald Trump has always been rather sensitive about this hair.
On several occasions during the 2016 election campaign, in an attempt to convince people it was real and not a wig, he asked people in the crowd to take hold and pull it.
So it it was something of a surprise when Mr Trump, in a seemingly unscripted moment, admitted that like many men of a certain age, he was struggling against baldness.
"I try like hell to hide that bald spot," the President said, taking to the stage at the Conservative Political Action Conference outside of Washington, as he looked at live footage that showed the back of his head.
Putting his hands on on head and smoothing down his hair, he added: "It doesn't look bad. We're hanging in."
Michael Wolff's controversial book, Fire and Fury: Fire and Fury: Inside the Trump White House, claims Mr Trump's eldest daughter, Ivanka, is among those who do not think much of the way the President styles his hair.
She is said to have "often described the mechanics behind it to friends", Mr Wolff wrote.
"An absolutely clean pate - a contained island after scalp reduction surgery - surrounded by a furry circle of hair around the sides and front, from which all ends are drawn up to meet in the centre then swept back and secured by a stiffening spray," it quoted her as saying.
Last year, Harold Bornstein, who is said to have been Mr Trump's long-term doctor for many years, told the New York Times the real estate magnate used a prostate-related drug to promote hair growth.
Earlier this year, Ronny Jackson, an US admiral and physician who documented Mr Trump's annual medical, reported the President was was taking Propecia, a medicine to prevent baldness.
This month, video footage of Mr Trump's hair being blown right, left and centre as he boarded Air Force One to travel to Florida went viral.
