Welcome to this bonus episode of the WhatsOnStage Podcast, brought to you by the West End production of Wicked. Last night, Wicked celebrated its 20th anniversary at the Apollo Victoria in the West End with a special celebration. While a certifiably joyous, hair-raising spectacle, the work being done on hair backstage is much, much more complicated – and pulled off with equal aplomb. We sit down with Wicked‘s head of wigs Heather-Jay Ross to reflect on the technical expertise happening behind the scenes, some of the incredible moments working on the show and some misconceptions about the world of wigs in theatre.
