After using the console command 'set timescale to 10' I have experienced a strange glitch in which the hair of a moving NPC (Occurs when dragging corpses as well) will float around near their head. As I have never had this problem before I would assume the console command is to blame, though I have had no luck fixing this glitch even after setting timescale back to 20 (default), reloading an earlier save, and reinstalling Skyrim.
Here are some pictures of the glitch for reference:
