Marionettes

"Victor Gabon" or "Baboon", (Vanessa Kirby ) the hair stylist doing The Queen's hair, was actually cutting-edge British hairdresser Vidal Sassoon, CBE. He opened his first salon in 1954 in London, and modernized women's hair styles. Sassoon created Mia Farrow's unique pixie cut for her role in Rosemary's Baby (1968).

Although this episode begins at a point after the main events have taken place, there's still an error with the Queen's hairstyle, of which much is made - both in the styling scene itself and Prince Philip's reaction to it. It's cut into the shorter, curlier style Her Majesty has favored to this day, but as the episode progresses, the hairstyle on actress Claire Foy reverts to the original, longer style.
