Okay, I loaded up Judy and looked at her material zones. She doesn't have separate eyebrow material zones. Her eyebrows are painted on, part of the face texture. I assume EJ is the same. Attach the face texture to Skinhead, and she should have eyebrows.

If the texture you are using is for V1/2, it may not have painted-on brows. I think you have to stick with textures that do have painted-on brows for Judy/EJ.
