Wow, I thought we were having an informative discussion

Trigger happy. :P I'm still interested in those data you mentioned. Topic is interesting.
Data aren't readily available but these might illustrate: http://blackhairclub.com/top-10-yaki-hair-extensions-on-aliexpress/ … http://goo.gl/dvZR92 http://goo.gl/P9D5ga
If you google "Caucasian hair extensions" you mostly get links to extensions *for* Caucasian ppl. None to, say, "black girl hair club"
But if you google "yaki", or "Malaysian hair extensions" or "Brazilian hair extensions", you get lots of links to black gilr beauty sites.
This is indicative of what's in demand due to texture, look, etc, not cost. If ppl wanted Caucasian hair theyd pay for it.
I have no particular opinion on the hair question, but I am interested in what people will select for using genetic methods when they become available in the near future.
