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.
Behind the scenes her hair was a major problem. The original Janeway actress left after 3 days of shooting and Mulgrew was brought in to replace her.
Mulgrew’s hair was so fine the cameras had trouble picking it up. They actually shut down shooting of the pilot to figure out how to do her hair.
Eventually they just had her in a wig or a half fall depending on the scene. Though I think that was like season 2 for the wigs.
