There is no doubt that Instagram is the go-to app for sharing selfies, pictures of gastronomic adventures, and a new haircut. This week, Bella Hadid and Kylie Jenner both revealed new hairdos. Jenner transitioned from a long, black mane to blond, shoulder-skimming tresses, to a blunt, neck-grazing chop that she debuted via a slow motion hair-flip video. Meanwhile, 18-year old Bella Hadid shared a BTS photo shoot outtake, where she channeled Winona Ryder’s Beetle Juice character, Lydia Deetz, via shabby, baby bangs. While Ariana Grande didn’t deviate from her signature half-up, half-down pony, she did send fans into a frenzy after revealing her new platinum blond tresses for her Focus album cover art.
