When I was like a baby, my hair was super short. By age 5 it was super long. Cut it all off and it was super short. By 8 it was long again. Cut it all off.
I've been doing this my whole life, going from ass-length to ear-length, as recently as last year.
Mine was down to my elbow, curly. And God knows how long straight. But I cut it last month and it's short-ish (well, comparatively) and manageable now.
