Loans arranged at the hairdresser's (5)
I believe the answer is:
'at the hairdresser's' is the definition.
'loans arranged' is the wordplay.
'arranged' indicates anagramming the letters (letters rearranged).
'loans' anagrammed gives 'SALON'.
(Other definitions for salon that I've seen before include "Place of business for eg beautician" , "Reception room - social gathering" , "Strange loans for a hairdresser, perhaps" , "Drawing room" , "Loans out as a reception room" .)
