“I wanted to make it lank and more lifeless,” the flick's hair department head said. “I f–king couldn’t. Harry’s hair is just so full of volume."
Now that the drama-filled "Don't Worry Darling" press tour is over, the singer is turning attention back to his growing beauty line.
"I decided let's create a lot of buzz around the film but not about the film itself," the "Big Mouth" star joked on "The Tonight Show" Monday.
Several "Don't Worry Darling" crew members and studio execs have denied a report claiming the director and leading lady got into a "screaming match" on set.
The pop superstar, 28, and the actress, 38, passionately kissed in the streets of Manhattan weeks after fans speculated about a split.
"I will always be grateful," Pugh wrote of the film via Instagram, shortly after it was reported that she and Olivia Wilde had a particularly bad fight on set.
"I think Harry Styles would be glorious," the raspy-voiced Broadway legend said about a movie version of his musical "Kinky Boots."
The couple had a lot to celebrate following the release of "Don't Worry Darling" and the end of Styles' residency at Madison Square Garden.
Pugh reportedly grew frustrated with Wilde's "frequent, unexplained absences" with boyfriend Harry Styles, who also stars in "Don't Worry Darling."
Styles' mother said she was "astounded and saddened" after reading comments left on her post about the highly publicized film.
