It's easy enough to bin hairs, with the binning tool in SimPE (I think it follows the newest version). Just look up the color binning tool at MTS2, and read what it says. I've done hair binning both the hard way (changing all the different bin numbers manually) and the easy way (color binning tool). It's easy enough to use even without much SimPE knowledge

Have you seen if you could find the original hair? It looks a bit like an XM hair.
You could download the sim, and check which mesh it is with the clean installer (NOT installing anything, just check). Then finding the original should be easy.
