No matter what I try, I have a problem when snow (particle sprite) passes in front of my character with hair (fiberfx) the hair disappears.

What do you think I'm doing wrong?

might very well be a bug, or limitation...

maybe fogbugz it (see my signature) or share the scene.

fixing it in post is another option...

My guess: FFX is a pixel/post filter, and IIRC doesn't support transparency, so your HV/sprites are running afoul of that somehow.

Try using PARTICLE INSTANCE snowflakes: I recently did it and it was very painless. And since they're instanced geometry, they should work.

Also, set up a test scene wherein you're controlling just ONE sprite directly, to subtract out any particle weirdness. Then you can try it in front/behind various transparencies and see what's what.
