What causes weird glowing lights in hair?

What causes hair to have weird bright colors in it when you render? I've been using the 3Dream engine and this keeps randomly happening. Usually, I'll spot-render the hair and it doesn't show again, but sometimes it does. It's very frustrating given how long hair takes to render in the first place. Any idea how to stop this crap from happening?

3Dream engine? I suppose you meant 3Delight?

What type of shadows do you use on your lights? From memory you can get that kind of colored artifacts when using shadow maps rather than raytraced shadows for big images.

I am using a 'deep shadow map' - is that the problem?

Yes possibly, try changing the lightds to have Raytraced shadows and see if it helps, it will increase render times though especially on anything with transmaps.
