How to Test if Hair is Human or Synthetic?

Jul 24, 2017

The most obvious way to determine if hair is real or fake is to conduct a microscopic test to find out the chemical composition of the extension hair.  However, since most of us do not a microscope readily available or have a degree in forensic science this is probably not a suitable option.

The textile industry conducts what is called a “fiber burn” test to identify the content. The same test can be done on hair.

1. Remove single strands of hair from different areas of the questionable unit.
2. Hold a single strand with tweezers and use a lighter to keep a steady flame.  
    Note: Do not use matches as they will mask the odor.
3. Pay attention to the odor, ember, and flame.

Human hair is a protein fiber that burns with a small flickering flame and will not continue to burn unless you hold the flame continuously to the strand. It burns briefly with an orange flame and then chars leaving a dark ash that turns to powder when crushed. The odor is of burning flesh or burning feathers.

Synthetic fibers are either nylon or polyester and each burns quite differently.

Nylon fibers burn briefly but rapidly and then melts. It has a sparkling flame that has a blue base and orange tip. The ash is like hard amber beads. The odor smells like boiling green vegetables or burning celery.

Polyester fibers burn and melt quite rapidly at the same time. It has an orange sputtery flame with black smoke and gives off a sweetish odor. The ash drips and is sticky to the touch before forming into hard black beads.
Remember to burn test each fiber separately as your piece may contain a blend of both human hair and synthetic
