Say your goodbyes to brunette Khloe Kardashian, because the bleach is back and blonde Khloe has officially made her return to the spotlight.

Sharing her colour in an Instagram post, Khloe wrote "Blonde KoKo is back" and judging from the amount of flame emojis, people could not be happier with her return to the light side.

The woman behind her new look is celebrity colourist Tracey Cunningham, whose clients also include Jennifer Lopez, Emma Stone, Margot Robbie and just about every other Hollywood star you can think of.

Tracey described Khloe's new colour as blonde "with some contrast" and included a break down on how she achieved the look.

Although, prior warning, unless you're a hairdresser this is not going to make a lot of sense to you.

"Redken Flashlift 30 vol 1/4oz. Olaplex on her virgin hair but on already lightened hair i used 20vol with 1/4 oz Olaplex after we rooted with #shadeseq 010n on hairline roots 08n+09nb 5 minutes."

The science bit aside, we love this modern blonde tone on Khloe. Rather than her usual warmer blonde shade, this is super cool toned with almost platinum silver highlights that give it that ultimate 'cool girl' feel.

As well as her new colour, Khloe got a new cut courtesy of Andrew Fitzsimons, who has had one hell of a week creating not only Kourtney Kardashian's '90s inspired MTV VMAs hair, but also Megan Fox's wet look MTV VMAs hair and Megan's Betty Paige inspired Met Ball look.

Someone give that guy a day off.
