For the past three years, Carpenter has been almost exclusively associated with bright, sun-kissed platinum blonde hair, a signature look that coincided with the massive commercial breakthrough of her 2023 viral single "Espresso" and her chart-topping fifth studio album *Emails I Can't Send*. The new look, a rich, cool-toned jet brunette that borders on natural black, marks the first time the 25-year-old has sported hair darker than a light honey brown in her entire public career. According to her long-time hairstylist, who shared behind-the-scenes clips of the coloring process on Instagram earlier this week, the transformation took more than four hours to complete, with multiple pigment layers applied to ensure the deep shade held evenly on Carpenter's previously bleached hair without turning brassy. The stylist added that Carpenter had been planning the hair switch for nearly six months, waiting for the end of her global summer tour to make the change to align with the start of her fall album promotion cycle. On the red carpet of the VMAs after-party, Carpenter paired the bold new hair with a floor-length, form-fitting black sequined gown, diamond drop earrings, and a minimal makeup look featuring sharp winged liner and a matte nude lip, letting the dark hair take center stage. Hours after the event, Carpenter shared a series of selfies showing off the new hairstyle on her personal Instagram account, captioned "dark mode activated for fall", which racked up more than 12 million likes in the first 24 hours of posting, with thousands of fans flooding the comments section to share their reactions. Beauty and fashion critics have widely praised the transformation as one of the most successful celebrity hair changes of 2024, noting that the deep hair shade brings out the warmth of Carpenter's skin tone and makes her signature cat eyes appear even more striking. Many industry insiders also point out that the hair change is a deliberate creative choice to signal the tone of her upcoming sixth studio album, which Carpenter has teased in recent interviews will feature darker, more introspective lyrics and a more mature, edgier sound than her previous discography. As of Thursday, the hashtag #SabrinaDarkHair has been viewed more than 380 million times on TikTok, with fans creating reaction videos, edit compilations, and even tutorials for recreating the exact shade at home.
