How to Distinguish Between Natural and Synthetic Hair

1

Burn the hair for the smell.

Choose a small strand of hair and burn it. If the hair is 100% human it smells like a barbecue; if not, it smells like plastic.

2

Check the ashes after burning the hair.

If the hair is 100% human, you can twist the ashes into powder; if not, the ashes will stay as a caking.

3

Heat the hair.

Use a flat iron to heat the hair. If the hair can be heated at 220 degrees and without a paste it is real.
Note: When you do such a test, a small strand of hair is enough.
