This year's Met Gala produced some incredible fashion moments – hello, Kim Kardashian's teeny tiny waist and Elle Fanning's ethereal gown – but if you looked past the gowns and the glamour, you might have noticed some new hair colours as well.Though Sydney Sweeney certainly took the trophy for the biggest hair transformation, opting for a short black bob complete with a full fringe, it was one blonde tone in particular that reigned supreme on the red carpet: a 'spun with gold' blonde.The shade was worn on Sunday night by Brie Larson and Rebecca Ferguson (and previously by Margot Robbie), who both looked radiant as they posed for the Met Gala cameras.Their Schwarzkopf Professional hair colourist, Jacob Schwartz, is the mastermind behind the shade – which we're predicting will be a big summer hair colour trend in salons – and he's since sent us over a description of what to ask for yourself if you fancy a gold and gorgeous transformation. He explains: "My version of the expensive "Monday blonde”, I call 'spun with gold' and involves a meticulously thorough amount of micro highlights throughout the entire hair.
