Export fully modeled Hair as OBJ

I know a few people have asked this, but I can’t find the answer to my specific question. I have a Spartain helmet (you know, the kind with the broom on top, like Marvin the Martian), and I have modeled the plume out of hair, and it looks great as a rendered still image, and I want to export it as an OBJ file.

When I click “convert” under the “modifier” settings, they just end up as strands with no pepth, as opposed to the nice, thick strands I created under the simulation.

How can I get what I see in the rendered image to export as an OBJ?
