I am a supplier of hair extensions and lace wigs from Qingdao, China.
In my hometown, there are more than 100 factories that focus on human hair extensions and lace wigs.
When I step into human hair business, people say it 3A, 4A. hair named Brazilian hair, Indian hair, Peruvian hair.
Now people say it 8A, 9A, 10A, 11A, you said it virgin hair, I said it one donor hair.
Is there such many kinds of different quality hair???
All as I know, some hair from India, some hair from Chinese women, some hair from North Korea, some hair from South Asia.
European hair? Russian hair? I saw some guys post pictures or videos on Instagram, but I never heard that even one factory buy these hair.
South American hair? impossible.
I had check Chinese custom data about these, none.
Your questions is meaningless.
Quality won’t different by people. just by how the hair come from.
I post a video of Indian hair.
you will know, it’s small probability event to buy virgin hair or so call one donor hair from India.
As I know, in China, most virgin hair source are processing for hair extensions, such as tape in hair extensions.
