A national top medical authority recently warned parents to take care in applying hair dye or perm products to children, as it may lead to safety concerns.
"For children, the use of hair dye and perm cosmetics will bring certain safety risks," the National Medical Products Administration (NMPA) said in a notice on Friday.
The notice came in light of the increasing popularity of children's hair dye products, many of which are used to "look stunning" in school stage performances.
