That looks pretty close but i don't think that's it, that one seems to have a right sided part-line and a pony tail and this one looks as if it's just pushed behind her ears
Zoom on the image and you can see aliased pixels around the hair and only the hair, and the sharp edges makes it look like this hair is a 2D resource. Even the highlights look like lazy airbrush strokes and don't really match the light source the figure is being hit by.
I see what you mean Coolcat. I also though that hair look kinda "off", like it was litteraly paint on the skull.
My second guess is that it is maybe just a "skullcap" surface texture from a hair which the author removed the opacity of most of the other layers.
If it is, good luck figuring out what hair it is. 🙁
At that point, you'll just be better off i thknk searching for hairstyle like what i liked to you in my first reply.
