Why not let teachers and students dye their hair and do manicure?

Hair dyeing and manicure are harmful to your health.

Hair dye and nail polish are both chemical components, which are harmful to hair and nails by acting on them.

Students are in the period of physical development, and there are carcinogens in hair dye and nail polish. Dyeing hair and painting nail polish are not conducive to the healthy development of students. Teachers should set an example for students in educating people, so the school will prohibit teachers and students from dyeing hair and painting nail polish.
