Hailey Bieber debuted her darkest hair color in more than 10 years on September 19, revealing a deep chocolate brown look just in time for fall. The Rhode Beauty founder showed off the glossy transformation in an Instagram post from hairstylist Irinel de León . De León handled Bieber's fresh cut and styling, while celebrity colorist Matt Rez took her hair from highlighted brunette to a richer, moodier brown. The finish arrived with Bieber's signature polished makeup and a glossy pout, because apparently one beauty statement at a time was not enough. How dark has Hailey Bieber gone before? Bieber's last notably dark hair moment came in 2015, when she wore a deep brunette shade with a blue mini dress at the Met Gala. Since then, Bieber has made smaller color shifts and even appeared with an icy blonde bob in March, a look that seemed to involve a wig over her caramel toned hair. The beauty entrepreneur previously told People in 2022 that her style philosophy was rooted in keeping things simple, while acknowledging that her approach could change over time. After welcoming son Jack, now 2, with husband Justin Bieber , Hailey Bieber also advised another new mom on TikTok to wait before making a major postpartum haircut decision, saying she planned to give herself at least a year before any dramatic change. Hailey Bieber's chocolate hair joins a larger celebrity makeover cycle this fall. The Secret Lives of Mormon Wives star Whitney Leavitt cut her long hair into a bob in September 2026, Connor Storrie swapped his Heated Rivalry curls for a buzz cut during season two filming in August 2026, and John Cena shaved his head before a second hair transplant procedure in June 2026.
