She has been fairly treated (8,6)
I believe the answer is:
peroxide blonde
'been fairly treated' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'she' is the wordplay.
I cannot really see how this works, but
'she' could be 'roxi' and 'roxi' is located in the answer.
This explanation may well be incorrect...
'has' acts as a link.
Can you help me to learn more?
(Another definition for peroxide blonde that I've seen is " She's changed the locks".)
