While elements of the ombré hair coloring technique existed earlier, ombré hair gained widespread popularity around 2010.
The "ombré" effect, characterized by a gradual transition from dark roots to lighter ends, didn't suddenly appear. The late singer Aaliyah had a subtle version of this in the 2000s. However, the trend really took off a decade later, becoming a prominent style in the 2010s. The style allowed for a bold and relatively low-maintenance look that resonated with many.
