Was there any change on your side regarding Unity version or renderer used? Are you trying to do this? (paste into canvas) http://paste.amplify.pt/view/raw/e30b7ef7 Hair shading is a hard problem to solve, it really depends of how far you intend to take it. If you want to keep using Cutout, I recommend using a Dithering pattern to attenuate the harshness; this is a common approach to this type of shader.
