Link is to the post where someone explained how to make a mirror morph within Poser. Basically, you turn it inside out, then reverse the normals.

The image is Male Hair 5, mirrored and rescaled a bit. (Texture is Koz's blond texture, desaturated.) Dunno if it would work with the Egypt hair, but it might be worth a shot.
