Jessica Chastain Short Hair, Bob Haircut on Red Carpet

Jessica Chastain needs no help stealing the show.

The Help actress debuted a bold new look at the 2026 Breakthrough Prize Ceremony in Santa Monica, Calif., on April 18, rocking a super short bob that fell just above her chin.

Chastain, 49, chopped off her long wavy locks before the red carpet, styling the bob with a dramatic side part and pairing the statement-making style with a golden Oscar de la Renta gown for the evening. While her hair was giving Hollywood glam, her dress leaned into some bohemian vibes with a palm print and thick tassel hemline. 

She later gave a behind-the-scenes look of the major haircut in a before-and-after video on Instagram April 19, captioning it, “Choppity chop.”

Her hairstylist Renato Campora celebrated her “fresh” style in a post of his own, while Chastain’s pals hyped her up on social media, including Julianne Hough, who wrote, “Welcome to the bob life.”
