Search for top stylist (4)
I believe the answer is:
comb
'search' is the definition.
(combing is a kind of searching)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for comb that I've seen before include "Common hair tidier" , "Hair-tidier" , "Red crest on a cock's head" , "For use on hair" , "Systematically search" .)
