Bushy hairdo (4)
I believe the answer is:
afro
'bushy 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 "Type of hairstyle - from Africa" , "Styling done to hair" , "Hairdo of the 1960s and 70s" , "Hairstyle adopted by the young Michael Jackson" , "Hair cut" .)
