Finally, I manged to find 3D Universe’s lovely Girl Scout Hair! It was one of a few things that seemed to have disappeared in the shuffle from one of the many versions of the site they’ve had over the years. There’s a few other goodies here too, such as Berry Hair for Koshini.
As near as I can tell, the name is supposed to be “Korin Hair 2” - it’s intended for “Korin 2 for MayaDoll” (the next link down on the page), but it appears to be a simple hair prop so it should be usable with any character with a bit of tweaking.
Edit, now that I’ve downloaded both files: Korin 2 Hair is a patch for the hair in Korin 2 - you’ll need both files to get the hair and all of its textures.
