If we are referring to the female hair, the specular value looks complete blown; too much specularity.  The other issue, as grichter posted, is baked-in specular highlights into the image map which is much more difficult to control.  Englishbob's map substitution solution is feasible, granted that the images are close to the same in detail, composition and resolution.  Without seeing the actual hair texture map, it will be difficult to suggest a solution.
