I love all the idols and I respect their respective styles, albeit sometimes you just can't help but shake your head at some of their choices...*shakes head*
Now the term 'crazy', is really wide, ambiguous and debatable. There is good crazy (not really that crazy though) - idols usually sport flashy hair colours or a myriad of different ones, almost like a rainbow. (I'm looking at ya Sehun) Their hairstyles are pretty tamed and even some of them are a definite HOT.
