This was a year to remember for the girls of Fifth Harmony.

They showed us who's "Bo$$," hit us like a "Sledgehammer" and proved that they have one of the most dedicated fan bases (shout-out to the Harmonizers!) when they took home their very first Video Music Award for Artist To Watch.

And with them every single step of the way was their signature move: the hair flip.

Each of these girls have a fabulous set of locks, and they are not afraid to use 'em. Whether it's on stage, in a video or just casually sitting in an interview, these girls have their hair-flip game on lock.
