Hairstylist Adir Abergel took inspiration from '60s hairstyles but gave it a thoroughly modern twist thanks to the addition of ombré hair extensions. To create the swingy ponytail, he started by separating the very front section of her hair and clipping it away. Then, he applied Virtue Unfrizz Cream (£19) and pulled the rest of her hair into a high ponytail. Up next, he wrapped ombré-coloured extensions around the base of Brown's natural ponytail (a step he said you can skip if you have long enough hair). Taking a large-barrel iron, he curled the entire ponytail, brushing the waves through once he was done to make the hair bouncy and shiny. He finished the look with more Virtue Unfrizz Cream on the front section, which he then wrapped over the side of the ponytail and secured at the base with bobby pins. A final spritz of Kristen Ess hairspray (£20) held the style in place.
