Anti-gravity hair-gel may be required. I've noticed that some of the women (such as senators and diplomats) in the prequels wear metallic "nets" or frames around their heads, but I'm not sure if that's for a structural purpose or for decoration. In other cases it's a ponytail where their hair is infuriatingly short for such hair styles. Is this just bad work with animation/wigs or some dark female magic? (I'm a female and I still haven't worked it out!) I was wondering if there was any speculation for how it would work in the real world.
P.s, The kind-of hair we're talking about here is "Queen Amidala's decoy"'s hair, which is so excessive it manages to make Princess Leia's hair in "A New Hope" look TAME! ;)
P.p.s: in series 3 episode 11 of Star Wars The Clone Wars ("Pursuit of Peace"), one of Padme's assistants is seen offering a wig/already complete hairstyle to Padme. It would appear some cheating is involved!
