Japan hates dyed hair, especially in school. Japanese schools, dyed hair is often banned. Even if it's your natural color, you might be forced to dye it black.
Some schools make students sign a form proving their hair isn't fake. And if it's too brown, too curly, too different, you get punished. The rule, everyone must look uniform.
No distractions, no individuality. It's not just about hair, it's about control.
