Hailey Bieber has once again caught the attention of her fans by debuting a temporary blonde hairstyle on Instagram. Known for her ever-evolving, trend-setting fashion choices, the supermodel gave followers a sneak peek at her throwback blonde look on March 21.

A Temporary Blonde Moment

In the Instagram post, Hailey shared a selfie featuring her blonde bob styled neatly with two brown clips securing the sides. The brief appearance of the lighter hairstyle sent her fans into a frenzy, as it harked back to her once-signature look of golden locks. However, the transformation appears to be temporary; in additional selfies included in the post, Hailey returned to her trademark dark brown tresses while enjoying quality time with her 19-month-old son, Jack.

The shift to blonde may evoke memories for those who followed Hailey’s earlier fashion and beauty moments. Before embracing a series of darker, shorter hairstyles in 2021, Hailey maintained blonde hair for much of her public career, solidifying her reputation as a versatile beauty icon.

Hailey’s Fashion Evolution

Hairstyles aside, Hailey Bieber has consistently matched her hair transformations with daring and memorable fashion choices. Most recently, she captivated onlookers at the Vanity Fair Oscars afterparty on March 15, 2026. There, she wore a custom Giorgio Armani creation that turned heads with its impeccable design.

Prior to that, Hailey nearly stole the spotlight at the Australian premiere of Weathering Heights, stepping out in a bold, nearly nude ensemble by Saint Laurent. These moments underline her willingness to push boundaries in the world of high fashion, cementing her status as one of the most talked-about style figures in Hollywood.

Then and Now: Hailey’s Hair Transformation Timeline

While Hailey’s blonde bob may be fleeting, it’s not her first time experimenting with golden hues. From her early public appearances to her red-carpet dominance, Hailey has seamlessly transitioned between light, golden locks and deeper, rich tones. She embraced the platinum blonde look prominently until 2021, after which she favored shorter, darker hairstyles. Each transition symbolized a new phase in her style evolution, earning her acclaim from fans and critics alike.
