Pilot Officer manufactured hair dressing (6)
I believe the answer is:
pomade
'hair dressing' is the definition.
(I've seen this before)
'pilot officer manufactured' is the wordplay.
'pilot officer' becomes 'po' (short for pilot officer).
'manufactured' becomes 'made' (I've seen this in another clue).
'po'+'made'='POMADE'
(Other definitions for pomade that I've seen before include "capital application" , "Oily dressing for hair" , "hair treatment" , "Perfumed hair dressing" , "preparation for locks" .)
