With the increasing demand from everyone, there are more and more types of wigs on the market. Some people would like to ask me how to choose real human hair.

Currently, if you want to determine if this is really high-quality hair, you can use the porosity testing method, which is also very simple. Go and select a small bundle of hair, stretch the end of the hair to make it smooth, and then use your hands to drag it from top to bottom to the base of the hair.
