Maroon hair (6)
I believe the answer is:
strand
I believe this clue is a double definition.
'maroon' is the first definition.
(as in stranding or marooning someone somewhere)
'hair' is the second definition.
(thesaurus)
(Other definitions for strand that I've seen before include "Scottish gutter" , "Leave helpless - length of fibre" , "Shore; single fibre" , "Beach or single hair" , "Leave in helpless position" .)
