Whenever hot weather makes me feel tempted to cut off a lot of my long hair, I remind myself that I can still get relief from the heat with a ponytail — a ponytail I wouldn't be able to do if my hair was short. Chloë Grace Moretz's approach to summer hair, on the other hand, is to just give in to the urge to chop a whole bunch of inches off. In fact, that's exactly what she just did, and it's making me question my stubborn insistence on keep my hair long.
