Good Chinese Hair Source?

Hi,

I have been working with a report at one of the New York papers.  She has done a lot of research into where the various types of hair comes from - India vs Russia vs other locations.  Right now she is wanting to talk with knowledgeable people about Chinese hair.  I was able to point her for Indian and Russian but really do not have a good source for someone that uses mainly Chinese hair for their extension work. Or any other non-Indian or non-Russian hair.  Mostly interested in Chinese at this point.  Or close countries to China.

Can anyone recommend some good people I might talk to about their work with Chinese hair?

Please email me at shelton@hairboutique.com or post here, whatever is easiest.  Anything said will be of the highest confidence unless you say otherwise.

Thanks in advance.
