There's the fake tan, short digits and the unnaturally pink lips, but Donald Trump's signature feature is without a doubt his hair.

How the Republican candidate came to sport such a boufant 'do has long been pondered. One recent suggestion is that his cresting wave is the result of a bizarre treatment for hair loss that lived and died in the 90s.

But what's lesser known is why Trump would opt for his particular shade of buttery caramel and signature "swoosh". That is until a photo of his late mother Mary Trump began circulating on Twitter.

One Twitter user shared the image with the caption: "I've only just realised Donald Trump is in a Nutty Professor-style family where he plays all of the characters."


The image, originally broadcast in 1997, is said to have resurfaced following the recent screening of Who is Donald Trump, a new documentary from Australian network Foxtel.
