Some that haven't been mentioned yet:
Glorious Hair - 3Dream (great transmaps and styling options, probably the most realistic looking full/long hair out there right now)
Bombshell V3 Hair - DAZ (an old standard for when I want big volume, but it doesn't always render so well, it could use better/updated textures and trans maps).
Moni Hair - RDNA

But I think I just purchased my new favorite, which a couple of people have already mentioned:

Wild Hair - DigiCalimero

The materials, textures and trans maps are simply the best I've ever seen to date on a hair item. Fantastic results. I highly recommend, and I think it's still on sale - worth every penny plus, one of the best Poser purchases I've ever made. Edited to add: However a really good, realistic long wavy/curly type hair is still needed. I can't work the hair room to save my life and the render times are too long for it anyway. I'd kill for a really nice long wavy/curly hair prop with top notch textures/materials/trans maps - that and more clothes for She Freak.
