'Bake' particle hair into a low-poly hair model with the Hair Factory by MajorNightmare.
Here’s an easy way convert Blender’s pretty particle hair into a Low Poly version Unity can use. The idea is to create an RGBA(w/alpha) TGA file that can be UV wrapped to a mesh object, and an FBX export to Unity. Essentially 3D to 2D hair.
There are enough tuts on FBX export to Unity, so google it.
2 example rigs. One method is a simple spine like rig that controls the entire mesh. The second example has a spine like rig for each mesh that makes up the entire head of hair for more control.
Using Unity’s image compression, you should be able to get the image fils size down to a couple of Kb.
