Margot Robbie’s 'mushroom blonde' hair is perfect for autumn – here's how to copy it

Margot Robbie has debuted a new, muted blonde hair transformation, and I was desperate to copy this colour myself, says beauty editor Laura Mulley. Here's how...

If she wasn't already my ultimate girl crush, Margot Robbie's new hair colour has certainly now put her at the top of my list.


While promoting for her new film A Big Bold Beautiful Journey, which also stars Colin Farrell, Margot debuted a new hair hue, swapping bright Barbie blonde for a cooler-toned, lived-in, 'mushroom' shade that's perfect for autumn.


Desperate to copy the look myself (and to be honest, look even a little bit like the Wolf Of Wall Street actor), I headed to my favourite salon, Haug London Haus, to see if my highlighted hair could be made to look anything at all like Margot's.


After showing her my inspo photo of Margot above, the salon's co-founder and award-winning colourist Siobhan Haug explained that the star's new look featured a lived-in, rooty effect featuring tones of taupe and beige, with brighter pieces around the front to shape and flatter the face.


On my hair, this could be achieved in two ways, she explained: either by leaving some of my natural colour at the roots around the crown and blending my existing full head of highlights into it (which would be a lower-maintenance method in the long run), or by taking the highlights all the way up to my roots, then cleverly creating the 'rooty' look with two different toners. As my hair is naturally very fine, it really benefits from the little added volume that bleaching my roots gives, and so I opted for this (Siobhan also explained that with this second technique, once the toner fades, I would still feel 'blonde', rather than my usual dark mousey brown shade coming completely through).

Following a full head of foils, Siobhan then applied a darker toner to my crown and lengths at the back-basin, and a lighter, beige-toned one to the front sections, followed by a bespoke hair mask and hot towel draped over the head. It's worth mentioned here that Haug London Haus's hair treatments are the best I've ever had; usually after having a full head of highlights my hair is incredibly knotty for months afterwards, but after the bespoke mask that they apply at Haug, my hair feels soft and easily detangled for weeks – a feeling that even lasted throughout a holiday during which my hair was subjected to plenty of chlorine, sun and seawater.

I was thrilled with the result: a gorgeous new tone for autumn – natural, neutral and grown up, yet still undeniably blonde and fresh. Now if only every other part of me could look like Margot too...

If you want to copy the star's 'mushroom blonde' for yourself, ask your colourist for a grown-out, rooty look at the crow, with the hair around the front kept brighter, and using neutral toner shades such as taupe and beige. Most hairdressers will still find photos the most useful way to know what you're looking for though, so don't be afraid to screenshot and save favourite hairdos to show at your next appointment.
