What Tailrustedtealeaf stated. I have one figure sitting right here.
I did managed to get the whole dig out thing but that was because I wanted to reposition AJ's leg personally, so I had a larger gap to work with. It was still a pain in the tail though.
As for the bobble head, you'd need to either cut the neck joint in the head itself at least most of the way around (also not fun). I removed the hair of mine after that and then decided for rehair it might just be easier to glue wefts into the rows like a model horse. So the option of removing the hair from the outside may be possible but I haven't tried it on the Fluttershy I have.
