Legal Analysis: Perms are not allowed in schools to comply with the law. The law does not clearly stipulate whether primary schools have the right to prohibit students from dyeing their hair. However, schools can have their own rules and regulations to regulate students' appearance. The Code of Daily Behavior for Middle School Students stipulates that students should wear neat and simple clothes, no perming, dyeing, no makeup, no jewelry, no long hair for boys and no high heels for girls.

Legal basis: According to Article 103 of the Civil Law of People's Republic of China (PRC), natural persons enjoy the right to the body. The personal safety and freedom of movement of natural persons are protected by law. No organization or individual may infringe upon the body rights of others.
