An 18-year-old student is suing for $20,000 in damages after her school told her to dye her hair black. The student went to a high school near Osaka, Japan. She had naturally brown hair. Her school told her to dye it black to follow the school's rules. A newspaper reported that school staff told the girl to dye her hair once every four days. She got a rash on her head and her hair became damaged. The girl also suffered from a lot of stress at school.

The student told the court that the school bullied her for three years. She was banned from school trips and festivals because of her brown hair. She said that teachers said things to her in class that embarrassed her. This caused her mental stress. She said that a teacher told her that she should not come to school with brown hair. The girl said that her stress made her collapse. She had to go to hospital by ambulance.
