You can choose a small strand of hair to burn. First, smell the smell. The real hair smells of roast meat, and the smell of plastic is easy to distinguish if you add heat-resistant silk. Check the ashes after burning, the ones that are ground into powder are real hair, and the lumps are wigs with heat-resistant silk.

The maximum temperature of the heat-resistant wire is 180 degrees -200 degrees, so you can choose a strand of hair with a straight clip or a point roller and heat it with a maximum temperature of 220 degrees Celsius to straighten or bend it. The burnt is the heat-resistant wire. What is unburnt is real hair.
