I'm sure she must have, but it's not talked about in the books. It wasn't a big plot point in the books, it was just mentioned in passing, although in the movie, they made a bigger point of it, likely for the high emotional feeling during the scene.
I have no doubt that Hermione cared about her parents, or else she wouldn't have done what she did, and that she was powerful enough to reverse any charm she put on them. No doubt it took her a while to find them after the events of the book, but I bet it was near the top of the list of things for her to do. In fact, in Chapter 6, she says the following:
I’ll find Mum and Dad and lift the enchantment. If I don’t—well, I
think I’ve cast a good enough charm to keep them safe and happy.
And, even more proof, here's a web chat with J.K. Rowling right after the release of the book:
Maggie Keir: Was hermione able to find her parents and undo the memory
J.K. Rowling: Yes, she brought them home straight away.
