Tangled: Before Ever After (2017)

What it's about

Rapunzel grapples with the responsibilities of being a princess and the overprotective ways of her father. While she wholeheartedly loves Eugene, Rapunzel does not share his immediate desire to get married and settle down within the castle walls. Determined to live life on her own terms, she and her tough-as-nails Lady-in-Waiting Cassandra embark on a secret adventure where they encounter mystical rocks that magically cause Rapunzel's long blonde hair to grow back. Impossible to break and difficult to hide, Rapunzel must learn to embrace her hair and all that it represents.
