Losing about 100 strands （縷） of hair a day is a natural phenomenon （現(xiàn)象）.However，if that number continues to increase and it appears the hair is not growing back，you may be starting to go bald （禿的）.
    More than 250 million people in China suffer （遭受） hair loss，many of whom are under the age of 30.According to a report，65 percent of the people aged between 20 and 30 use hair tonic （生發(fā)水）.80 percent of those aged 30 and above have suffered hair loss.
    Staying up late，long-term unhealthy work patterns （模式），and the pressure of work often make young people suffer hair loss.In order to prevent hair loss，Mr.Wang，who graduated from a top university in Beijing，said he had tried lots of ways to grow his hair，but found that his hairline （發(fā)際線） is getting higher and higher，and the hair is becoming much thinner. "Once the hair becomes thinner and hairline becomes higher，anyone who sees me for the first time thinks I'm older than I really am.For us young people，this is awful，" he said.
    So it is common for people who are under 30 and suffering hair loss to begin wearing wigs （假發(fā)）.The owner of a wig shop in Beijing says the number of young people visiting the shop has risen from 10 percent a couple years ago to 30 percent now. "In the beginning most of the customers were middle-aged and elderly，" the owner said. "In recent years，there have been more young people，especially men，with hair loss."
