Uncombed and untidy (7)
I believe the answer is:
unkempt
'uncombed and untidy' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for unkempt that I've seen before include "Badly turned out" , "With neglected look" , "Slovenly" , "Looking untidy or neglected" , "Not neatly combed" .)
