For now days, the hair products become more and more popular among ladies, but some supplier may use synthetic hair to replace human hair or mixed the synthetic hair in the human hair to reduce their price. How to identify its human hair or synthetic hair, here are two ways.
First is using the microscope. If the hair is synthetic, it is made from a form of plastic that will appear clear when lit and magnified under a microscope. Natural hair that has never been dyed will have a solid core and clear outer layer, while dyed natural hair will have solid color throughout. 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 better way to test it is burning. Remove single strands of hair from different areas of the hairpiece or wigs. Hold a single strand with tweezers and put a lighter flame to the end of the hair to ignite it and then pull the flame away.
Pay attention to the smell and the way the hair burns. Human hair has a distinctive sulfuric odor. When it is lit, the flame will flicker out quickly unless you continue burning it and the ash will be powdery.
Watch how synthetic hairs burn. Synthetic fibers will continue to burn up quickly after you've taken the flame away. Polyester hair burns and melts at the same time, has a slightly sweet smell and leaves sticky beads on your fingers. Nylon hair smells like cooked vegetables and will burn up quickly with a sparkling flame, leaving hard beads behind.
By learning this, it will save us both time and money to test it.
