Lady Gaga's hairstylist says he cried after she asked him to dye her hair brown for 'House of Gucci'

• Lady Gaga's hairstylist Frederic Aspiras told People he cried after dying her hair brown for "House of Gucci."
• Aspiras said that her signature platinum blonde by Joico Blonde Life Color is "most her."
• Aspiras created 10 wigs and a "500-page directory" detailing all of the hairstyles in the film. 

Lady Gaga's hairstylist and friend of 12 years, Frederic Aspiras, told People he spent months emotionally invested in creating the hairstyles for Gaga's character Patrizia Reggiani, in "House of Gucci."

Aspiras recalled an instance where he started crying after she asked him to dye her hair brown to prepare for the role.

"We re-dyed her real hair from her platinum signature blonde hair back to brown months before the movie was shot, just so that she could feel be in the character," Aspiras told People's Daniela Avila. "I mean, you're talking about someone who is so devoted to characterization and the art that she willingly wanted to color white hair."

"It was past her shoulder, it was very healthy, gorgeous, and wanted to color it brown. And I was so besides myself. I was crying," he added. "I was like, 'Are you sure about that?' 'Like, yes.' And we colored it brown."

Aspiras told the outlet that out of her many hairstyle incarnations, the signature platinum blonde by Joico Blonde Life Color is "most her."

The film, which was released on November 24, centers on Reggiani, who was convicted of hiring a hitman to kill her ex-husband Maurizio Gucci, played by Adam Driver, in 1995.

Aspiras told People that preparing various hairstyles worn by Gaga throughout the movie was a five-month process that required him to undergo extensive research on Italian women of that period.

"I sat with that script at my house during COVID, and for five months I went script page by page and thought of the characterization of the person, the inspiration of what this hairstyle was going to look like for that scene, and the actual real-life photo of Patrizia at that time," he told People.

His work resulted in 10 wigs and a "500-page directory" detailing all of Gaga's hairstyles. Aspiras said his work on the film was a "passion project."

Aspiras told People that Gaga's only request regarding her look was, "I don't want to see Lady Gaga on the screen!"

Representatives for Gaga and Aspiras did not immediately respond to Insider's request for comment.
