Sorcerer returning natural hair (7)
I believe the answer is:
warlock
'sorcerer' is the definition.
(thesaurus)
'returning natural hair' is the wordplay.
'returning' shows that the letters should be reversed in order.
'natural' becomes 'raw' ('raw' can be a synonym of 'natural').
'hair' becomes 'lock' (lock is a kind of hair).
'raw' back-to-front is 'war'.
'war'+'lock'='WARLOCK'
(Other definitions for warlock that I've seen before include "Cork law about male witch" , "Charmer" , "Male magician - British composer, 1894-1930 - low rack (anag)" , "Wizard, magician" , "Magician; Peter ---, composer" .)
