My theory has been that her hair is where she stores the energy she builds up from her Semblance, so shorter hair means less storage space, which means that she can't pull off a super powerful attack from putting everything she has in one punch.

As for her Semblance getting triggered when someone messes with her hair, we've been shown a few times now that overwhelming negative emotion can cause someone to use their Semblance by accident. Yang does it almost every time she gets angry, even if she's not in combat. Pyrrha did it against Jaune. And, finally, Weiss did it at the charity ball.
