Vamp explored in bed without love: she not really being fair? (8,6)
I believe the answer is:
peroxide blonde
'she not really being fair?' is the definition.
(person who isn't really fair-headed)
'vamp explored in bed without love' is the wordplay.
'vamp' indicates an anagram (vamp can mean to repair or modify).
'without' is an insertion indicator ('without' can be similar in meaning to 'outside').
'love' becomes 'o' (In tennis, 'love' means 'zero').
'explored'+'in'+'bed'='exploredinbed'
'exploredinbed' is an anagram of 'peroxideblnde'.
'peroxideblnde' placed around 'o' is 'PEROXIDE BLONDE'.
(Another definition for peroxide blonde that I've seen is " She's changed the locks".)
