I'd say it needs to be low maintenance since I have extremely long hair (ends just above my hip), and therefore almost never have the time to do any styling. But at the same time I want it to be (and look) healthy, without having to keep it shorter. :)
#2 Maybe others don't consider it long, but since I have so much longer hair than any of my friends, family etc. it's what I count as long. :) But no, compared to knee-long hair, it's definitely not long.
