Following coiffeuse's article, hairdo's neat (5)
I believe the answer is:
uncut
'neat' is the definition.
(thesaurus)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for uncut that I've seen before include "(Of a diamond) rough" , "Without abridgement" , "Not sliced" , "the whole pack" , "Not truncated" .)
