long hair short hair, it depends on how comfortable u are with the hair.
altho i must say, hair can make a person look quite different. i was at this Pink live gig in a club. After the gig, I was in the loo when this gal standing at the sink asked me:
"hey u're that girl who was on stage next to pink playing the guitar right?"

she prob mistook me for that gal because we both had long black hair and a dyed fringe(pink in my case, red in the case of the guitarist). altho i sure dun deny i wouldn't mind being that guitarist, seeing as how she shared a french kiss with Pink onstage
