Mental Ray Shadow problems ( mia shader with cut-out opacity )

I am problems with my shadows in the hair area.
The hair is modelled with planes and use opacity maps.

My setup is the following:

Rendering in Maya 2013 with Mental Ray.
The geometry has mia shader, lots of colour information is coming via the additional colour. Opacity map is hooked up to cut-out opacity.
I am using FG and Area lights with ray-traced shadows.

My shadow method is set to segments in the render globals.


It looks like the shadow are not coming through the transparant parts of the hair. Anybody know a solution ?

EDIT : Solved : Upped the trace depth of my shadows in the area lights that solved the problem. I removed the image.
