Well the sites that did all the Feng Ye videos also do haircut videos and report(irregularly over years) on whether people still have their long hair or whether they cut it. I think Feng Ye's newest video and photos were 9 months ago from chinalonghair so in all probability she still has the long hair. That site appears to be down at the moment but it's youtube channel is still up. My favorite was Zhang Huan, but I heard she cut it unfortunately, supposedly their are more long hair videos and photos to come though.
