My favorite part was how her hair was in a beautiful and much more complicated knot in the premier episode, then it was a mangled mess after Voyager was thrown to the Delta Quadrant, but they make a show of her fixing it into the simpler knot with her bare hands while walking the corridors from one disaster to another.
Janeway commands, and her hair obeys.
That’s what transporters are for. If you’re going to die and a replica who thinks it’s you is going to appear someplace else there’s no reason it shouldn’t be styling some great hair.
