As mentioned here by Pooklet, the skull on the original mesh, did not play nice with shaved alphas. At least in shape anyway. So I replaced Nouk's skull with the original maxis skull, and Pooklet, being the delightful person she is, editted the result so that the hair sat properly on the new skull.
So yes. This is merely a mesh replacment, you'll still need somebody's textures for this to work (mine or Nymphy's will work) and you will need to delete the original mesh. DELETE IT. Or else it will not work.
I'm also working on a female version for this, I think it'll look pretty good :P
