It's not so long ago that they had "hair police" here. Not at immigration unfortunately but on the streets. They'd grab a bunch of teenagers who had the audacity to dye their hair or get a weird style. Then they'd hack the girl's hair up or shave the guy's hair off, but deliberately do it badly so it looked terrible. I remember it happening to a guy I knew, and still know, from a Cham family. The family are very wealthy and hold high posts. He was doing some silly teenage gangster business down at a local high school, fighting and stuff. They were all rounded up and given the chop. He's behaved himself since, studied abroad and is a fine upstanding member of society now. That shit doesn't work for everyone though. In my own teens skinheads were a thing. They were great in high school, the teachers used to get really annoyed because they couldn't grab your sideburns anymore.
