Why have dynamic and shifting hairstyles, from Katniss Everdeen's Power Plait to JoJo Siwa's outsize bows, become such a significant part of how girlhood is articulated in contemporary visual cultures? What do they tell us about how girlhood combines the qualities of resilience and sparkle needed to survive and thrive in turbulent post-recessionary times? Drawing together analysis of popular film franchises, Disney animation, ground-breaking TV shows, music videos, girl celebrity personas and global art cinema, this book shows how across different cultural levels and aimed at different audiences, girls' hairstyles provide a complex dynamic site of interpretation and interaction. It documents the careful craft of hair-dressers and software engineers working in the screen industries to style and animate hair, bringing their work to a new visibility. It is in the very everydayness of hairstyling that we come to understand girls as the most resilient and the most sparkly of citizens.
