A Chinese woman dyes her hair 1.9 times per year, while the number in Western countries is 5, according to the China Hair Report released last week.

Co-launched by China Consumers' Association, China Hairdressing and Beauty Association, and the global cosmetics giant L'Oreal, the report says hair coloring is a big sector in the country, and will become much more profitable in the future, especially in the next five years.

"Many Chinese consumers still have a bias against hair dye," says Yan Xiuzhen, president of CHBA.
