Interwoven length of hair (5)
I believe the answer is:
plait
'interwoven length of hair' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for plait that I've seen before include "Stranded piece of hair" , "Interwoven length of hair" , "Braided hair" , "Hair braid" , "Interlaced length of hair" .)
