Episode 4 - S1.E4

Sarah auditions for the part in the movie, but doesn't get it. She then meets with her agents and they tell her that she needs to change her look (they tell her to dye her hair purple). She does so, and hates it. Her friend then changes it back, but makes her hair shorter, and Sarah says it's better but she doesn't like it. Her agents call again, offering her a role (requiring her to have the purple hair), which she turns down and decides that she wants to try out the "normal" life.
