We can distinguish from the following aspects:
- In terms of price:
Synthetic hair is made of rayon by machine, with low cost and very cheap price. The human hair is made by hand with real human hair materials, and the cost of raw materials and labor is high, so the price is more expensive.
- In terms of weight:
The quality of synthetic hair is heavier and the comfort is worse. Real human hair is thinner and more comfortable to wear.
- In addition, there is a more scientific method:
You can cut some human hair and synthetic hair and burn them with fire. When the synthetic is burned, there will be black smoke and a pungent smell, and it will become lumps after burning. There is no black smoke and pungent smell when burning human hair, and it becomes powder after burning.
