Most are professionals, Tmall says, dealing with customers, colleagues and subordinates at work, dressed immaculately and with fine hairstyles. However, in the evening they browse wig shops and hair improvement shops on online platforms buying all kinds of wigs or hair nutrient products.

At present, there are mainly three types of wig materials on the market, namely chemical fiber, the cheapest, real hair and chemical fiber mix more expensive, and human hair, the most expensive.

Chemical fiber wigs are the most common among cosers－those who indulge in cosplay-who wear colorful hair at various animation exhibitions. The tough texture makes it easy to knot after washing and is difficult to manage. You can buy a whole top set for a few dozen dollars.

Wigs made of a mixture of synthetic filaments and real human hair have a more natural look. Most of the wigs costing between 300 yuan and 1,000 yuan sold on Taobao are of this type, with the ratio of real hair to chemical fibers being 4:1.

Real-hair wigs are the most expensive, usually costing thousands of dollars, and more advanced wigs are even customized according to personal hair color and hairstyle needs. These wigs, of course, look the most natural, and as long as they are worn properly it can be difficult to distinguish them from a real head of hair. In addition, they stand out from the other two types of wigs, being more breathable and absorbing moisture.
