Hair for in-game rendering can be a tough beast to master. Alpha blending is usually required to get soft feathery edges, but can cause sorting problems. Lighting can also be difficult, so hair is usually rendered using an emissive shader (without any lighting at all). If the hair is being lit, options include bent vertex normals, normal mapping, and anisotropic mapping.
