You're lucky. We have "hair codes" at my house and they state:
-No dyed hair under ANY circumstance (they say it's a distraction and that it's too expensive and a pain in the ass)
-Maximum hair length for boys: Halfway down the nose
-Maximum hair length for girls: Unknown
-Minimum hair length for boys: Unknown
-Minimum hair length for girls: Shoulders (they say it'll be more masculine if it goes any further up)
No wolfcuts.
No bangs unless you're a dude.
