While Lady Gaga's makeup evolved through each era in the film, her hair colour played a crucial role in indicating her status at any given moment. In the beginning, for example, it was meant to look like she could have done it herself.
"For her as a young woman, she was not yet part of the Gucci dynasty, so she wouldn't be able to afford to go to a very high-end salon or have a hairstylist and we wanted the colour to reflect that," said Aspiras. "Most likely, she would have done her own hair at home, because she lived at home. And she worked for her family, so it had to be a colour that was pretty rich and natural, without any highlights or any type of colour services. Back then, there was no balayage and whatnot, so we had to stay just almost beautiful virgin brown hair."
As the years went on, and as Patrizia gained access to money and power, her hair colour would eventually go on to become indicative of the trends at the time — all created with Joico pro hair colour. (Aspiras is an ambassador for the brand.)
"These were all subtle [hair colour] changes that contributed to the character, her emotional state, where she was in her life, her status."
"For instance, the 80s was when she moved into more of a power look because she was now married into the Gucci dynasty. Back then they got their hair coloured in this really rich, shiny, near-black colour. These were all subtle changes that contributed to the character, her emotional state, where she was in her life, her status. We went from beautiful, shiny brown, well-kept hair, to by the end of the movie, it was dry and fried, short, and she looked like she gelled it back herself, showing her almost unhinged state."
(It's worth noting that in the aforementioned era, it wasn't just the colour that screamed "power" — it was also Lady Gaga's perm. That, "Father, son, and the House of Gucci" perm. "The look wasn't about having the ringlets, but rather the frizz and curls," he said. "We would style with mousse and water to change the integrity of the curl, then brush it out. [Lady Gaga] kept saying, 'Ugh! This is ugly,' and I would say, 'Oh, it's tragic, but that was the look.'"
