I'm working on a scene with a lot of dust and it seems that the dust storm is affecting my character's hair making it transparent. If I lower the output of the dust storm, it helps eliminate the transparency, but then I don't have enough dust in my scene. Is there any way to keep the dust storm particles from affecting hair at all?

I still haven't found a way to have dust storm effects ignore hair so it doesn't make them transparent. Anyone have any ideas?

I think there's a setting to "Correct Transparency" in Preferences under "Real-time Render Options".  Worth a try...

I'm not in the studio now, so can't check it out or apply screenshots but, if you have this possibility in your storm, try to change the Blend Mode from your dust from "Alpha" to "Addition"...
This only works if you can change this "Blend Mode"...
Popcorn FX does not have this, so another way to do this (as far i know) is with "Alpha Threshold".
Enable "Alpha Threshold" on your hair. Try around with the slider. An amount of 40 and maybe a "Self-Illumination" of 70...

If you can't get the blend mode idea to work ------- This might not be an applicable idea for your project but you could make two renders. One of the hair it self and one of the scene props and avatar. Then merge the two videos ! 

As toystory mentioned...I usually have to turn on Alpha Transparency to correct that issue. It's not idea as far as the hair looking good goes but you have to decide which is worse I guess
