Hair color.

We’re used to seeing in-demand model besties Gigi Hadid and Kendall Jenner the other way around: Gigi as the green-eyed blonde and Kendall as the dark-haired beauty. But at the Balmain show this week that was topsy-turvy, courtesy a bit of backstage hair magic. You might also notice an uncharacteristically dark-haired Rosie Huntington-Whiteley, blonder-than-normal Alessandra Ambrosio, raven-haired Lily Donaldson, and others. See all the hair…

A hair colour change is the perfect foundation for a drastic makeover or reinvention; and if you’re going use hair colour as a statement, going platinum blonde – or near to it – is certainly a striking way to do it. Looking at the key hair trends for 2013 and beyond, bleached blonde in it’s lightest incarnations sits high on the list, partly thanks to…

With perfectly groomed brows, winged eyeliner and a flicked-up 1960s style blonde bob, Barbara Palvin looks utterly divine. This sneak preview comes via her instagram account from behind the scenes on a photoshoot. As for which shoot, we’re not yet sure. But we can’t wait to see it.

Abbey Lee Kershaw has largely been absent from modelling, having been off working on the fourth instalment of the Mad Max movie franchise. This photo is a preview of her now pink hair, apparently died for the film.

Change is good as a holiday, so they say, and to extend the maxim you might add that drastic change for a model is as good as a new career.

It’s no longer a hair trend, but the idea of ‘just change it‘ is never out of fashion.

For fashionisers in the Northern Hemisphere currently experiencing autumn's cool days, it's not too late for either a minimal seasonal update or total colour revamp that will take you into winter 2012.

The notion of ‘just change it’ when picking a new hair colour remains just as relevant as we approach the final quarter of 2011 as it did when the year kicked off. Seemingly channeling Madonna, Russian model Sasha Pivovarova joins the white blonde set in her outing on Vogue Paris’ October 2011 cover.

We’ve long said that 2011’s hairstyles are first and foremost about one thing: changing the colour. Model Natalia Vodianova has since joined the changed set, covering the September 2011 edition of Vogue Turkey as a peroxide blonde.
