Human hair extensions sell at a premium on account their maintenance and lifespan advantages. This has given rise to spurious claims of manufacturers trying to pass of synthetic hair extensions as original human hair extensions to be able to pocket the differential profit. It has become imperative for discerning customers to be able to tell the difference apart if they do not wish to be cheated. The simplest means of checking the genuineness of human hair extensions is by conducting sample strands to a burn test. While genuine human hair extensions emit an orange flame when burning and leave behind a dark ash, synthetic hair, which is mostly made of petrochemical origin plastics, burns with a blue base, not unlike the flame in cooking gas. Further, while human hair extensions do not burn when the flame is removed, synthetic extension fibers burn completely once they catch fire. Human hair extensions smell like burning hair when burning, while synthetic ones emit a sweet smell. Another means of testing the genuineness of human hair extensions is by subjecting them to a detailed examination under a microscope. This requires an elaborate laboratory set-up which is not readily available to general public.
