This, as David said, helps reduce the spill problems. You could also try using a polarizer to see if you can "dial" out some of the reflectivity of the hair.
The best approach is just to have enough distance from your talent to screen.

but when we try anything on our Velocity Q's, it just has trouble getting rid of that notorious green halo.
The chroma keyer in the Velocity Q is quite poor. I know, I have one.
I always use the new Master Keyer in Smoke to pull chroma keys. With a good green
screen it is usually one click and I am done.

Make sure you have detailing on your cameras turned off because that can create edging which when keyed can look like a halo at times.
Sometimes people think it's good to send some backlight on the actors to separate them from the screen... don't do this - it makes a natural looking composite impossible and has a "haloish" effect - unless the scene itself is set that way
But from the follow-up comments - it really sounds like it is your software. All compositing software is different - kelight, primatte, and ultimatte all work pretty well, but I prefer keylight as ultimatte is pretty uncontrollable and it's spill killing creates awful artifacts.
