Look in the freestuff under contributor's name "ffabris". He has six white-on-black "hair transparency maps" for use on Mike figures in Bryce. This approach is costly in memory terms, you need to have 2 Mike meshes, one for the regular texture and one - slightly larger - for the hair transparency. Looks VERY real when rendered, but eats RAM like crazy. I took one and inverted it so the hair would be black, then just took that part and layered it on another texture of Mike to custom make a hairier tex I needed. This is the best way to go if you want "free". If you're willing to part with some $ for higher quality, go for one/some of Quimabella's Mike character/textures in the store - definitely high quality. I recently bought his "Carlos Forte" - not particularly hairy, but a great character and damn goodlooking.
