Hers
Possessive Pronoun
Use 'hers' to show that something is owned by or belongs to a specific female person mentioned earlier. 
No 'Her' Before
'Hers' is used alone without 'her'. Saying 'her hers' is incorrect because 'hers' already shows possession. 
Not Replaceable
'Hers' cannot be replaced with 'her' when indicating possession at the end of a sentence.
