So, there's some good stuff in Pierre Woodman's videos of long haired women. The problem is that it's easy to lose track of the good stuff and a lot of it gets buried in the history.
I must've gone over many hundreds of girls whose pictures looked like they may have very long hair. I've collected what I consider to be especially hot (normally waist and longer at the time of casting), and offered links to the official videos on Woodman's site. For full pirated stuff you'll have to look elsewhere on the net.
I don't know whether there are any extremely long-haired girls he's fucked or shot films of. The longest here are probably Kinuski, Sandra Luberc (this is almost the longest she's ever had!), Lovenia (before the cut!), and of course our contemporary porn princesses Mary Rock (before her big trim) and Andreina de Luxe. Lara Fox's full scene is yet to be released. 
If you know of stuff I've missed please don't hesitate to add!
