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 an anagram (letters rearranged).
'loans' with letters rearranged 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" .)
