Braided hair (5)
I believe the answer is:
plait
'braided hair' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for plait that I've seen before include "Braided pigtail" , "A twine of hair" , "Rope-like length of hair" , "Braided hairdo" , "Stranded piece of hair" .)
