Virgin hair is chemically unprocessed human hair, also known as Pure virgin hair, it has to be 100% pure.
It cannot have gone through any kind of chemical processing, so when you purchase this hair, it has not been permed, colored treated, dyed, bleached, blow-dried, gone through any other chemical processing.
It’s from one single donor so each bundle you buy should from the same donors(the donor could be Indian, Malaysian, Brazilian, etc). This has not been exposed to any kinds of harsh agents and the cuticles all still have to be intact and running the same direction.
If these things are not so, this is not true virgin hair.

Here’s why virgin hair is chosen: The Highest Quality Hair(But Most Expensive), Last Longer than any other types of hair extension.
