Question: Why is it that Tracy's hair keeps getting more and more highlights through scenes?
Chosen answer: It's common for filmmakers to subtly alter a character's appearance throughout the film to reflect how the character changes. In this case, as Tracy comes out of her shell, her personality becomes brighter, stronger, and more pronounced, and that is shown by her increasingly lighter hair.
Answer: I believe her hair is also symbolic of white and black integration.
