Her hairstylist Harry Josh, John Frieda International Creative Consultant, gave Rose a hairstyle that was 70s-inspired with a modern twist. Think Michelle Pfeiffer in Scarface meets a modern-day Anna Wintour.
To get this look right you need to spend time getting the hair straight and sleek. Josh sprayed Byrne's wet hair at the roots with a volumising mousse, he used John Frieda Full Repair Protecting Root Lift Foam, £5.69 () lift that was weightless. I needed to get a lot of lift at the roots, says Josh. Without that, the look would just fall flat.
Byrne's new haircut is very blunt, so Josh applied a small amount of John Frieda Full Repair Perfect Ends Deep Infusion Serum, £6.99 () to the ends to ensure the end result was super-smooth.
Josh then used a natural bristle brush to blow-dry the hair section by section. His top tip: Always angle the dryer downward for maximum shine and minimum flyaways.
To finish the look, Josh used velcro curlers to curl the ends under. At home, use heated rollers on the ends and leave them in until they have curled to set the hair in place. LouisvuittonShop loves Cloud Nines The O Ultimate Set, £179.95 (at ).
