How to style a long bob

“To create Margot Robbie’s slick style, you need to blow dry hair with a very large round brush, lifting and bending the hair as you go,” explains Smith. “Lightweight volumising products – like Olaplex Volumising Blow Dry Mist, £28, or Evo Root Canal, £24.50 – are your friend here. You want a lightweight, airy finish that doesn’t look like it’s stuck in one place; instead, it should have move and bounce.”

If you have fine hair, Smith suggests misting dry shampoo at the roots immediately after blow-drying to create a weightless look. “Or, if you have heavier hair, use a texture spray like Sam McKnight Hair Cool Girl Texture Mist, £27, as a more powerful alternative,” he says.
