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 it’s synthetic, it will smell like plastic.
2. Check the ashes after burning the hair.
If the hair is 100% human, you can twist the ashes into powder; if it’s synthetic, the ashes will stay as a caking.
3. Heat the hair.
Use a flat iron to heat a small strand of hair. If the hair can be heated to 220 degrees without becoming damaged, the hair is 100% human hair.
