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.
