Dont use Paint Effects for hair... Use Hair for Hair. paint effects never really worked for me and it looks sooooo false on a render...

I am not too mush of a fan of Paint Effects for stuff and anything I do use it for is converted into polys/nubrs.

Steve (GSter123) love hair and may be able to give you better tips than I can. I use Joe Alters Shave n a Hair cut for hair. Way better and so much fun.
