Bob or afro, for example (6)
I believe the answer is:
hairdo
This clue is a double definition.
'bob' is the first definition.
(bob is a type of hairdo)
'afro for example' is the second definition.
(afro is a kind of hairdo)
(Other definitions for hairdo that I've seen before include "capital arrangement" , "Cut and set" , "that may go with a bang?" , "Bob, perm or bouffant" , "What one may have expected from 'Sweeney Todd'" .)
