I have a 12 year old daughter (turns 13 next month) who has just informed me that she'd like to dye her hair green. Sigh. I asked if maybe she just meant green streaks? Nope. She wants all of it green. Um, okay. Told her I would need to think about this. I guess there's nothing technically wrong with it but all of it? Green? Do they even sell over the counter green hair dye?!?
