Holds hair (5)
I believe the answer is:
locks
This clue is a double definition.
'holds' is the first definition.
(locking is a kind of holding)
'hair' is the second definition.
(locks can mean hair)
(Other definitions for locks that I've seen before include "Securely fixes" , "raising devices for sailors" , "Door fasteners" , "Secure fasteners for doors" , "Clusters of hair" .)
