Donald Trump's hair secrets revealed in new book, based on Ivanka's descriptions

One of the President's most noticeable features explained

The “mechanics” behind Donald Trump’s hairstyle are illuminated by his daughter Ivanka Trump in a new book.

The President’s orange-yellow crown is perhaps his best-recognised physical feature. And according to a new book plumbing the inner workings of his presidency, it was also a target of mockery for his daughter and top aide.

Ms Trump “treated her father with a degree of detachment, even irony, going so far as to make fun of his comb-over to others,” Michael Wolff writes in a new book that was excerpted in New York Magazine.

As it turns out, its hue may be influenced by Mr Trump’s personality. Per Ms Trump, the colouring product the President uses darkens the longer it stays on.

“Impatience resulted in Trump’s orange-blonde hair colour,” Mr Wolff writes in Fire and Fury: Inside the Trump White House.

Establishing the President’s hairstyle is more than just a matter of colour, with Ms Trump reportedly described an elaborate process to friends.

Mr Trump starts with “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 and then swept back and secured by a stiffening spray,” Mr Wolff writes.

The White House has already blasted other claims made in the book, lambasting former top campaign strategist and aide Steve Bannon - who is quoted describing a campaign meeting with Russian emissaries as “treasonous” - as someone who “has nothing to do with me or my Presidency,” who has “lost his mind”.
