Hair-down-to-there has been grazing the rear ends of celebs like J. Lo and Ariana Grande for the last few years, but longer-than-usual ends are going to make a huge appearance on everyone in 2019. Few people are lucky enough to to be able to get this look naturally (even with all the magical hair growth potions out there), but a good salon can source you some extralong extensions. "Longer hair will be a lot more manageable because it's going to be about effortless texture instead of structured waves," said Leal. " It's also great for accessorising with hair clips and hats."
