The Spring Breakers star first showcased a caramel dip-dye, before updating her look with hints of burgundy and golden blonde.
Now she's upped the ante by making her autumnal ombre hue even more vibrant!
The starlet unveiled her stand-out look while attending the Unbound Access Presented by Hearst Magazines event in New York last night (15 October).
The tips of her tresses were coloured a burnt orange, which graduated into a warm red before returning to a deep brown.
She let her bold mane do all the talking by rocking a simple white blouse tucked into a leather pencil skirt.
Vanessa seems pretty taken with her new barnet, Instagramming a selfie with the caption: "Killin the season game thanks to @hellobeautifulsalonnyc #spiceitup #fallLeaves #youngandfree."
She also posed alongside a tree covered in autumn leaves, saying: "My hair has finally found its home #vermont #fallcolors #obsessed."
Vanessa was joined at the event by Miranda Kerr, who looked equally as gorgeous in a mirror print bodycon dress.
Unlike Vanessa, she showed off a more conservative hairdo, adding electric blue heels and a slick of red lippy.
What a stylish twosome!
