Here is my best explanation:
'beauty parlour' is the definition.
('salon' can be a synonym of 'beauty parlour')
I can't explain the rest of the clue.
(Other definitions for salon that I've seen before include "Reception room in grand house", "Strange loans for a hairdresser, perhaps", "Drawing-room", "Drawing room", "Parisian art exhibition", "Hairdresser's premises", "Loans (anag.)", "Elegant reception room", "Literary gathering" and "Elegant room is great house for entertaining".)
