Does Bamboo (Fargesia Robusta) Regrow its leaves

Hi - I saw Beechgrove the other week where Carole cut out a number of the canes at ground level to thin it out, and then she took off the lower leaves on the canes so to open up the bottom of the bamboo.  Perhaps a silly question, but once cut off, do those leaves re-grow (making it a regular task to do), or once they've gone, they're gone for good?  I know canes don't regrow!
