personally, money would be more important to me than having long hair. lol. i agree with a lot of people saying what does hair have to do with someone's job performance. but also, i don't see what the big deal would be about having short hair as opposed to long hair. dunno, i started growing my hair out before... and it was just too much of a bitch to take care of so i got rid of it.
good luck with job man. hopefully, i guess, you won't have to cut your hair
