CAS meshes (hairs, accessories, clothes) need joints, so you have to import the full Unimesh/SimPE mesh into SimPE.
You can export them to a meshing program as OBJ, but you have to fix the joints before importing them back to
SimPE as Unimesh. Preferably with Milkshape, but Blender with plugins can work (not sure if the Blender exporter still has issues with normals).
If you export the mesh as OBJ from SimPE, also make sure the UVmap doesn't "jump" up or down from the marked UV square, because when you export CAS meshes as OBJ from
SimPE they sometimes tend to do that, which will make the mesh show up without texture if it isn't fixed (the sim material shaders don't tile). It's easy to fix - you can usually move the entire UVmap one full square up/down with some kind of auto tool, it's possible in both Milkshape and Blender.

A somewhat quick "what to do with OBJ-exported hairs" tutorial:
- If you export the original hair as a GMDC/SimPE/Unimesh file and import it to Milkshape, you'll have the skeleton and the "hair" group (back of head), plus the original hair for comments and group names (very useful)
- Keep the "hair" group for the back of the head (should stay unchanged)
- delete most of the geometry in the "hair-alpha" (but keep the actual hair group for now, this is just so Milkshape doesn't flip out when you import the OBJ file).
- Import in your OBJ file.
- Place the OBJ group where the hair-alpha was in the group lineup.
- Copy the name of the original "hair-alpha" over to this group (probably has a different name than hair-alpha, I'm just calling it that here).
- Also copy over the comments from the original group to the new one.
- Copy over the joint assignments. If you want to keep it simple, mark the entire new "hair-alpha" group, go to the "joints" tab, choose the "head" option from the first (!) dropdown list (there's four of them, don't do anything to the others), crank it up to 100% and choose "assign". If the original hair had more fancy assignments, you can try to copy it, but that requires a bit more finesse.
- Now you can export the file as Unimesh/GMDC and import it into SimPE.
- Rinse and repeat with the other ages.
