How to distinguish between the real hair and the synthetic hair?
1 If the hair is natural ,it will immediately catch fire and burn nearly instantly ,curling into a ball. It will have a strong, somewhat unpleasant smell. Synthetic hair ,on the other hand , will slowly melt rather than burn, and will have almost no smell.
2 Feel the textures, each strand of natural hair is coated with scales. This means that the hair is smooth if you pinch and rub it moving downward ,but resists and feels different if you rub it the other way. Synthetic hair is smooth whichever way you rub it.
3 Burn. Human hair will be ah after burning and will show white smoke while burning .Synthetic hair will be a sticky ball after burning and will show black smoke.
