Hines moved to Los Angeles, California to pursue an acting career, and began by doing improvisational comedy at The Groundlings Theater. Among the people she studied with was Lisa Kudrow. She also learned to write comedy sketches, which served her well in her experiences with Larry David in the TV show Curb Your Enthusiasm on HBO. The show is written as retroscripting in which the plot outlines are generally and loosely drawn and the individual characters improvise to create the dialogue.

In July 2006, Hines received an Emmy nomination for Outstanding Supporting Actress in a Comedy Series for her work on Curb Your Enthusiasm.
