"New hair alert very important," she captioned a video showcasing a fresh colour and cut, having opted for a blonder, long bob with a feathered finish - which could almost be described as a '70s 'shag' (minus the fringe).
Teigen tagged her long-term colourist, Tracey Cunningham (who also works with the A-list likes of Jennifer Lopez, January Jones and Emma Stone), who appears to have taken her honey tones to a brighter, buttery shade.
Recent photos of Teigen have seen her sport long, chest-length hair (see below), although these likely come courtesy of extensions.
Still, her new 'do is certainly a significant style update for the star, and one we predict will be channelled by many come 2020.
