It’s true that the U.S. president and Britain’s next prime minister both have very prominent blonde hair that has become part of their public personas, but there the similarity ends. President Donald Trump’s hair is very carefully styled before he appears in public, with each strand put in its proper place to give him the look that he wants. Boris Johnson is precisely the opposite. From the start of his political career, and in the journalistic scramble that preceded it, Johnson has sported what could be called the “slept-on” look, declining to comb or style his locks in any way so that it has a natural, spontaneous and even unpredictable quality. It’s not a $300 Hollywood concoction by a celebrity stylist, it’s an accident-in-progress. The forward plunge of his hair takes something from the “moptop” look of the early Beatles, but the Beatles’ locks were always washed and carefully combed, while Johnson seems a stranger to such conventions.
