Issue with rendering hair

I was making a head and had all the materials/particles/and everything done and I would render it is and it would work awesomely. Then I started working on rigging the head and when I finished (last night) the hair would not render, no eyebrows no hair. Its driving me insane, I can’t figure out why. THe only thing I could think of was pushing the little button in the particles tab that says “enable particle system during rendering” and it still wont work. Can someone please help me?
