I'm a little stuck... Click here to teach me more about this clue!

But I can't explain it at all! Could you help me understand?

(Other definitions for hairdo that I've seen before include "Bob, perhaps" , "Bob, perm or bouffant" , "Say, crew cut" , "What one may have expected from 'Sweeney Todd'" , "Style of coiffure" .)
