Lili Reinhart Debuts Brunette Hair for Upcoming Film Role

Lili Reinhart has debuted a dramatic brunette hair transformation as she prepares to star in and executive produce the film adaptation of Ali Hazelwood's novel The Love Hypothesis. Departing from her signature blonde look made famous by her role as Betty Cooper on Riverdale, Reinhart's new brunette hair is styled in a relaxed bun, mirroring her character Olive Smith, a biology PhD candidate. She shared the change on Instagram and TikTok, where she humorously referenced the film's plot involving a fake relationship between Olive and her love interest, Dr. Adam Carlsen, played by Tom Bateman. The film is directed by Claire Scanlon and produced alongside Elizabeth Cantillon, with Reinhart expressing excitement about this new chapter that showcases her versatility as an actor. The novel's author praised the team involved and expressed trust in their adaptation of the story. Reinhart's hair change also represents a personal reset, as she has noted the toll her previous blonde hair took on her natural hair health, making this transformation both a professional and personal milestone.
