Going platinum blonde is a marathon, not a sprint — and Hilary Duff's newest hairstyle just seriously backed up that fact. The actress took to Instagram to reveal her brand new, icy blonde hair color, and judging off her caption, the transformation was an all-day affair.

"'Twas a long long day but the mission was accomplished," she wrote alongside a selfie that featured her platinum lob, which was created by Riawna Capri and Nikki Capri, the gurus behind Nine Zero One salon. This is also the first big hair change that Duff has made since giving birth to her daughter, Banks Violet Bair, at the end of October.

While Duff was a blonde before, this shade creates a dramatically different look. Prior to going ice blonde, Duff was wearing her hair in a honey blonde shade with darker roots. She might have chopped off a few inches in the process of going platinum too, as the selfie draws attention to her face-framing layers.

For the record, Hil... The all-day dye job was definitely worth it.
