How come Jennifer Grey didn't become a big movie star after DIRTY DANCING?

I saw Jennifer Grey in an interview not that long ago, I think she was promoting her memoir, and what a lovely woman she is. Also ageless, she didn't look a day over 40 yet she was in her 60s. She always looked younger than she was. In DIRTY DANCING, she was pushing 30 but played a teen and was convincing at it. No Gabrielle Carteris.

For some reason, the movie, while a huge hit, didn't make her a movie star. She barely worked whereas Patrick Swayze became a huge star.

And it always seemed unfair to me since Grey had the bigger and more difficult part to play. And she was so good. She was a scene stealer in the supporting parts she took prior to DD, Ferris Bueller's sister for example, but after DD, she was over.

And the nose job didn't ruin her career since that happened 8 years after the movie.
