It's not her aura, it's her semblance. And I think she stores some of the energy from previous battles in case she needs it later. When someone cuts her hair, she becomes angry and uses the energy she's been storing. It's possible that the energy gets stored in her hair, I guess. So, if her hair gets cut short, she won't be able to store up much energy at all.
