Jessica Chastain Just Chopped Off Her Signature Long Hair and Looks Stunning

Jessica Chastain is the latest celebrity to cut her hair short in the biggest haircut of the summer.

Jessica Chastain just got the biggest haircut of the summer.

Jessica Chastain is the latest in a slew of our favorite leading ladies to cut her long hair into a bob, further indicating that this hairstyle is the look of the summer. Earlier this season, Mila Kunis debuted her now famous bob and baby bangs, and since then we've seen Selena Gomez, Vanessa Hudgens, Hailey Baldwin, Margot Robbie, and more celebrities rock a tousled short hairstyle.

The 41-year-old, usually standing out to fans with her striking golden-red locks, revealed the big change on her Instagram account today, captioning the image, "Summer Cut." She tagged hairstylist Renato Campora, whose own account also posted some action shots mid-transformation of him trimming strands around the actress' face.

Campora was Chastain's hairstylist before the drastic shakeup as well, many a time creating those classic Hollywood waves you drooled over (and might miss just a little).

But Chastain is definitely in good hands (and scissors) with him when it comes to styling her new short 'do, too. The celebrity hairstylist posts photos frequently of other A-list women he works with who have haircuts to similar to Chastain's, and they always look fresh and somehow more stylish than the last.

Kunis–whose hair he styled last night for the MTA Music Awards–and Robbie are on his Instagram a lot sporting their bobs in seriously inspirational ways.

Chastain's departure from old Hollywood glamour to chic bob may make her less recognizable at first, but I'm already at the point where I stare at any woman with a slightly unkempt bob to figure out if it's someone famous.

Yes, the look is that popular now, and it will be all summer. I would bet hair clips on it.
