If 2017's opal hair, Elsa from Frozen and iridescent strobing somehow got together to have a beauty trend love child, it would be this.

Yup, we're talking Holographic Hair.

Somewhere between all out rainbow and last year's grandma chic grey hair trend, holographic hair is all about subtle pastel highlights that catch the light giving the impression that your hair is magically changing colour. Dreamy.

Championed at US hair salon Ross Michaels Salon, the multi-tonal look is achieved by using Olaplex to help lighten the hair before streaking it with a mix of different Pravana dyes in Violet, Luscious Lavender and Blissful Blue to create a rainbow of muted silver and pastel purple tones.

Add to that a whole load of shine and you've got yourself the metallic hair trend du jour.
