The strawberry blonde quiff has remained, through wind, rain, hail, or shine, seemingly immovable, perpetually fixed in that unique Trump style.

It has, in a presidential campaign that seems to have commenced at the dawn of time, taken on a life of its own.

The internet has feasted well upon speculation the unwavering Trump tresses may not be altogether natural.

Even The Simpsons weighed in.

“Donald, I want to ask you, because next time I see you, you might be President of the United States,” he began.

“I just wanted to know if there’s something we can do that’s not presidential, really, or something we can do now that we’re both civilians.”

Trump appeared hesitant.

“Like what? I’m not liking the sound of this,” he replied.

“Can I mess your hair up?” Fallon asked, to wild laughter from his audience.

“The answer is yes but the people of New Hampshire, where I’m going to be in about an hour, I hope they understand,” Trump replied.

To the delight of audience members, Fallon then went in for the tussle, proving once and for all, Trump’s hair is firmly attached.

It also left him looking like the crazy uncle who always tried to kiss you hello.

Democratic presidential candidate Hillary Clinton is scheduled to appear on Fallon’s show next Monday.

It is unknown whether her own perfectly maintained hairdo will be subjected to the same treatment.
