Orange Hair Is Trending in Hollywood — and It's Just What the Colourist Ordered

Throughout the film, you can see as Ally (played by Lady Gaga) transforms into a pop star for the masses — bright orange hair included. Her onscreen love interest may not have been into it, but if you were, it's easy to re-create: "Orange is an easier colour to achieve because a lot of times you don't always have to use bleach, depending on the lightness or brightness you are going for," Brown said.

"I'm partial to the soft apricot colour myself, which is easy to achieve if you're already a blonde with at-home dyes or conditioners. Overtone makes a pastel orange, which is really pretty."

Another great option to try if you're after that softer effect: "Bleach London has awkward peach or blorange you can try," Brown said.

While the Aquaman movie won't be released until December, there's one thing you couldn't miss after watching the trailer back in July: Amber Heard's megabright orange hair, which is likely the works of a great wig. "The [hair industry] makes great wigs now, so you don't even have to dye your hair to try it out, like Kylie Jenner and Amber Heard," Brown said.

Game of Thrones's Sophie Turner is a hair-colour chameleon — going from blonde to brunette to red in a snap — but she channels her inner Sansa Stark in the new Dark Phoenix film.

While Suspiria — director Luca Gaudagnino's attempt at remaking Dario Argento's giallo film — may sound scary enough to keep you from seeing it in cinemas, you'll want to go for Susie Bannion's (played by Dakota Johnson) fiery hair alone.
