What should I do for Terri Lee?

Mumpy Terri Lee has her original wig, but it's not aging well.  It looks okay from the front...

...but it's losing hair badly on both sides.  The thin spot is close to her temple here.

I don't know if y'all can see it, but the back of her dress is covered in blonde fibers.

What should I do for her, y'all?  Do I leave her current wig alone and cover the bald spots with ribbon, or should I shoot for a new wig?  eBay has a couple'a options, but I don't think they look right for Terri Lee.  Hmmm...I think I just answered my own question.  But I'll ask y'all anyway:  if this was your doll would you leave the wig alone or look for a new one?

Love,
