‘It’s inspired by Brigitte Bardot, it’s a bit Jean Shrimpton,’ Hersheson told ELLE. ‘I looked to those sixties icons for inspiration.’

Hersheson admits that it wasn’t the toughest job in the world, ‘she’s super gorgeous, so it was just about making her look really hot.’

To get the look right, it was all in the prep. ‘I spritz her hair with L’Oreal Professionnel tecni.art Pli, £12.60 (at lookfantastic), then used a good hairdryer and a round brush to blow-dry. I wanted the hair to have lots of depth and guts.’

Once the texture was in place and the hair blow-dried with plenty of volume, Hersheson started adding plenty of height at the crown with a hefty dose of backcombing. ‘This gives you the basis to play around’ he said.

Kunis’s hair was side parted at the front and styled to frame her face. ‘Hairspray was used in excess’ Hersheson said. ‘The style was then really brushed out with a Hersheons Mixed Bristle Oval Cushion Brush, £24’.

The key to getting this look right is to play around and find a shape that suits you but echoes the sixties style Kunis rocks so well on the cover.
