While Duff didn't share more context on exactly how she achieved her new look, one can only imagine that a potent hair colour mask was involved. On her Instagram story, she gave a better glimpse of her style while bathing her daughter, showing off her naturally dark roots, and blue highlights where her blonde ones used to live. Her new look immediately got tons of reactions from fans and friends, including her colourist Nikki Lee of NineZeroOne salon in California. "Yep! You did it!" Lee wrote, co-signing the look with a heart-eye emoji.
