If you want to distinguish between human hair and synthetic hair. The method is very simple.
In general, use fire to burn.
After the fever is over, the ashes can be crushed. And thefibers will harden after they are burned.
The smell of human hair and synthetic hair burning also make a big difference.
When professionals engineer check whether there are fiber hair in the hair, the common method is to use electric splints to detect, specific methods:
1, plug the electric splint into the power supply.
2, adjust the temperature of the splint to a maximum of 220 degrees.
