I think it will be depend on how much tissue damage was done. Ruby had an abscess on her neck that was big (almost ping pong ball size

) after it healed she had a bald area about the size of a half dollar. It's been 1 1/2 years ago and now she has a pencil eraser size area that doesn't grown hair there. But, with all of her other long hair it's not really noticeable.
Your girl will probably grow most of the hair back, and it should cover the tiny area that may not grow....it will take time though.....be patient.
