Seeing as most of the "Don't Worry Darling" cast are wearing wigs in the movie, you might be wondering why Pugh, the lead character, isn't. Well, the answer is simple: Pugh's natural hair is straight-up perfect the way it is.
"We knew that we wanted to use Florence's hair because she has a gorgeous head of hair," says McIntosh. "She was already light, so we just adjusted her hair colour a little. [Her hair] holds the curls so well and bounces beautifully."
The main inspiration for Alice's hair was 1950s French actress Brigitte Bardot, whose voluminous blond hairstyles became her trademark. In the film, Pugh wears a variety of period-appropriate styles, most notably a half-up pouf with face-framing bangs. She's also seen in glamorous updos and for a scene in ballet class, a decidedly Bardot-inspired black headband and ponytail. McIntosh said she used the Oribe Dry Texturizing Spray ($24) to achieve Alice's coiffed volume.
"Every time I strayed from Bardot or tried to find some other type of reference, we always just ended up going back to Bardot," McIntosh says. "And then we found all the gorgeous little accessories that would kind of pop against her blond hair. We just had so much fun with it."
