Brown-haired (8)
I believe the answer is:
brunette
'brown-haired' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for brunette that I've seen before include "She's certainly not blond" , "Dark-haired woman" , "She's certainly not a blonde" , "Kind of dark girl" , "girl unlike Goldilocks?" .)
