I managed to fully remove the furry parts from the head, and I'm trying to do a headswap with a ZinFit because the original body is way more tedious to work with. Unfortunately, I suck at Blender and it looks really bad. Armature and stuff works but I don't know much about UV or textures, since I had to extrude a lot of parts to make it fit with the neck.
If anyone more knowledgeable wants to try to fix it, let me know. I'm kind of losing my patience over it.
