Hairstyle brought back in superior fashion (4)
I believe the answer is:
afro
'hairstyle' is the definition.
(type of hairstyle)
'back in superior fashion' is the wordplay.
'back' says the letters should be written backwards.
'in' indicates the answer is hidden within the clue.
'orfa' is hidden within 'superior fashion'.
'orfa' written backwards gives 'AFRO'.
'brought' is the link.
(Other definitions for afro that I've seen before include "shock treatment?" , "Big hairstyle" , "little Malian, for example" , "Roundish hairstyle" , "Tightly-curled 4 down" .)
