Hairy bunch (4)
I believe the answer is:
tuft
'hairy bunch' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tuft that I've seen before include "Bunch of hair, feathers, grass etc" , "Small bunched cluster" , "Bunch of hairs" , "Dog's lead" , "Handful of hair" .)
