Parting hair on character head

I modeled a character head in blender 2.57 and now I am trying to add hair. I was following a tutorial for blender 2.49 and most of the directions were fine except for creating a part. It says to mark the seam where you want the part and then click “Use seams” in the children tab. However, in 2.57 that option doesn’t exist. So does anyone know a good way to part hair in 2.5?

Thanks a lot,
