Seafront centre hairstyle (4)
I believe the answer is:
Here is my best explanation:
'hairstyle' is the definition.
(afro is a kind of hairstyle)
'seafront centre' is the subsidiary indication.
'centre' says to take the centre.
The centre of 'seafront' is 'afro'.
(Other definitions for afro that I've seen before include "Luxuriant (black) hairstyle", "Hairstyle with little thick curls", "Hairdo of the 1960s and 70s", "Hairstyle with tight curls", "Style of haircut", "Hair style", "Hairstyle adopted by the young Michael Jackson", "Of hair style, tightly curled and bushy", "Hair in tight curls" and "Hair-style from Dark Continent".)
