Tapered hairstyle
I believe the answer is:
fade
'tapered hairstyle' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for fade that I've seen before include "Grow faint and disappear" , "Deaf (anag.)" , "Gradually grow faint" , "Lose colour or vitality" , "Droop" .)
