Every hair in place (4)
I believe the answer is:
neat
'every hair in place' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for neat that I've seen before include "Trim - tidy - without water" , "Alcoholic drink without a mixer" , "Well-trimmed" , "Tidy and spruce" , "without water being added" .)
