I would be interested in where your basis for this sentence comes from. Wars have been fought by people with long hair...i'm not talking the line up and shoot each other wars either. I'm talking weapons with edges and fists, The Celts, The Native Americans, The Barbarian tribes of Germany, the Japanese, the Mongols, etc. I would like to know in what way long hair is impractical, if you're a practiced martial artist or combatant, you don't let people get close enough to grab it. (I know this is way away from the basis of the subject, but I couldn't look at this as a valid argument for her overall look in the film)
You can fight with long hair just fine, but it is something you must worry about when you're in a fight. It's another grabbing point for your opponent to control and limit your movements, and it doesn't even have the advantage of also potentially being a weapon like your limbs. And it can blind you if it ever escapes whatever tie you have it in.
I'm not trying to say it can't be done, but it requires you to pay attention to your hair and the positioning and momentum of your head. Essentially, it adds another layer of complexity to a fight that really doesn't need to be there and gives you no gain.
Having long hair in a fight is purely a disadvantage. There is no possible advantage to doing so. Thus, it's not practical to have long hair in a fight.
