Curly hairdo (4)
I believe the answer is:
afro
'curly hairdo' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for afro that I've seen before include "Roundish hairstyle" , "Styling done to hair" , "Type of 18" , "Hairdo of the 1960s and 70s" , "Shock description" .)
