Oh yes, I agree - there is no 'real' virgin hair ventilated in these lace fronts - though this may have been in case years ago.
When I get my Virgin Brazilian .. it's really just a name they call another kind of Indian hiar. I can look at:
Indian remy (the shinest and poorest color quality)
Indian virgin (much better but still rather shiny)
and
Brazilian virgin (a much lower luster version of the Indian virgin so less shiny) and the actual hair strains are THINNER. That's why I like the Brazilian virgin.
Color?
Indian remy ? If I get 1b it looks flat and one dimensional .. because it's a dye job
Indian virgin ? looks better - but still...
Brazilian virgin? Is the best because (they claim) it is the natural color so you see the slight 1b and 2 color variations - especialy in broad daylight. So it looks much more natural.
Moral of the story .. I wouldn't believe that the actual hair you buy from CV or even AV is anything other than Indian or Chinese

- it's a marketing gimmic. But all Indian and Chinese people do not have the same texture of hair so .. that along with different processing .. basically causes the hair to look differemt - thus the exotic names like Peruvian or Mongolian or Brazilian.
What's in a name tough? Like they say ... 'a rose by any other name .. is still a rose'.

I say - just figure out what you like best and order it.
