The Oscar winner debuted her cut at the Breakthrough Prize Ceremony event on April 18, walking the red carpet sans her signature long, flowing red waves. In their place was a chin-length, blunt-cut bob courtesy hairstylist Renato Campora, who documented the process on Instagram if you want to see the cut in progress. Prior to the event, Chastain's hair fell to about mid-back, but now it just grazes her jawline. Campora styled it straight with a slight bend to the ends, parting it deeply to one side with a portion of hair brushed slightly over one eye.
