Please be gentle?
OK, wil try..

Please, please, please remove ALL AO everywhere you can find it.
Remove all AO from all lights, and or all materials.
AO is fake.
AO is fake IDL and is from previous Poser versions when there was not IDL yet.

You have the real thing = IDL, render with IDL.
Raytrace bounces 2-3
Pixel Samples 3-4

Also try; I do not know the hair u are using but try;
Connect the hair texture into Bump at .5 (my Poser units are inches, chech yoursà
Connect the hair texture also in Displacement at 0.1 in inches

Testrender with IDL in render settings, with ONE single pure white infinite light with NO AO.... :-)

Happy Posering
