Be aware that resetting Unity will remove your desktop/launcher customizations and bring all open windows to the first virtual workspace. –  LexLythius Jan 15 at 14:58

Open compiz config settings manager from a terminal using the command

ccsm

Then go to the desktop section and click on the unity desktop plugin and select enable.

After a few seconds the top & side bars should re-load.
