Needlewoman, note, getting in Sam's hair (10)
I believe the answer is:
seamstress
'needlewoman' is the definition.
(I know that needlewoman can be written as seamstress)
'note getting in sam's hair' is the wordplay.
'note' becomes 'e' (musical note).
'getting in' is an insertion indicator.
'hair' becomes 'tress' (tress is a kind of hair).
'e' inserted within 'sams' is 'seams'.
'seams'+'tress'='SEAMSTRESS'
(Other definitions for seamstress that I've seen before include "needlewoman" , "Dressmaker" , "Woman who sews for a living" , "Midinette" , "sewer" .)
