Human hair wigs are completely different.
Human hair wigs will not show black smoke when they are lighted. After burning, they will turn into powder.
What about a real human hair mixed with chemical fiber and having a fever?
We used 70% real hair mixed with 30% synthetic fiber to burn. There is no obvious black smoke after burning. The taste is also the smell of burning hair. Turns into powder, and some are black hard palate. So the real human hair mixed with chemical fiber filaments has both powder and black lumps.
There is actually a way to distinguish real human hair without burning. For example, the reflection of synthetic hair is much stronger than the real human hair, which is very unnatural. The hair dye for real hair and wigs can be directly colored, but the synthetic hair is not. The real hair wig is OK. With high-temperature curlers or splints, synthetic fiber hair is not enough. But the most scientific and direct method is to burn it with fire.
Using the scientific method to test the material of the wig in your hand is the most reassuring method. Don’t believe in the truth when you hear it outside.
