Raleigh, at sea, produces something for shock? (4,3)
I believe the answer is:
hair gel
'something for shock?' is the definition.
(shock can mean a mass of hair)
'raleigh at sea' is the wordplay.
'at sea' is an anagram indicator.
'raleigh' is an anagram of 'HAIR GEL'.
'produces' is the link.
(Other definitions for hair gel that I've seen before include "style fixer" , "something for shock?" , "This used to set" , "Fixer of locks" , "Application for styling job" .)
