I'm nopt really into poser, but I think that eye lashes are normally made with a texture and a trans-map. I think you could try that too with the hair. And maybe, if you have the software. you can import the poser figure into C4D (I've heard that it does much better imports than Bryce) and add hairs with a plug-in. There's a plug-in that makes hair from polygons. I don't know how it's called, but maybe someone else can help you with that. If you make the hair from polygons in C4D than you can export these to bryce. It's probably not the most common way of doing it, but I can't think of anything else at the moment. Also photo-textures make the poserfigure look more real and lighting can add a lot to the figure.
