Well if you rotate the station to get gravity I would still call it artificial.
I know that in Elite there are no Gravity Generators like in other Sci Fi settings.
But I am quite sure with about 1000 years of experience living in space and low gravity that people and the industry would have found a way for the ladies and Guys to keep their long manes.
What comes to mind for example would be braiding "heavy" beads into it to keep it flowing in the direction of the gravity forces.
Some heavy duty hair sprays would work as well
In the morning earth, midday in the cockpit and in the afternoon on the moonstation and always looking good, use our patented hairstyling sprays.
With our Anime princess showing off her locks, I am sure there is quite a big interest in Empirial space into having long hair for many ladies.
And Denton Patreus sports the classic pirate dreads, in fashion for outcasts and privateers since the Pirate of the Caribeean movies
