"I don't even think that's possible, even if you want to... It is all a kind of slightly sensationalised piece of news that comes out and gets highlighted, which more often than not turns out to be baseless," Katrina told IANS in a telephonic interview from Mumbai.
Regarding her hair colour and style in the film, Katrina said that it was the director's idea "with a symbolic connection".
"This was an idea which Abhishek had. The thought behind it was when the leaves fall in Kashmir and the whole ground turns red... It was a symbolic connection as the colour red signifies passion, love and fire," the "Phantom" actress said.
"We took a lot of pictures and a lot of discussion and once we had locked in on the hair colour, and then just took one day to do it and shot the whole film in three to four months. Then I dyed the colour back, and it was black again," added the actress, who recently launched L'Oreal Paris's new La Vie En Rose signature collection.
Katrina has even issued a statement denying the rumours around her multi-million hair colour, which according to the gossip mills could have been used to fund education for several students.
"The wonderful thing about being an actor is that people are interested in what you do. But there are also lots of misleading and untrue articles that also come out. And because I am not on any social media platform yet, I don't have the chance to contradict every rumour.
"The team who worked on my hair, did a great job. It was a great idea put forward by Abhishek. As kind and wonderful that our producers are, I don't think they are that kind. I don't think I would have been very nervous had Abhishek not been very confident in supporting me."
London-based hair expert Daniel Galvin, who has worked on tresses of celebrities like popstar Madonna and the late Princess Diana, was roped in to work up the magic on Katrina's tresses for the film.
Even the film's director has clarified that there's no truth to the Rs.55 lakh story.
"I can't help but smile when I read these speculative reports of money spent on Katrina's hair. They are outrageous. But what's important is Katrina and Tabu (who also sports red hair) both look amazing and in my humble opinion, their hair even more so. So let's just compliment the ladies," Kapoor said in a statement.
"Fitoor` is an adaptation of Charles Dickens classic novel "Great Expectations" and will have Katrina playing Firdaus, while Aditya Roy Kapur will portray the character of Noor.
The film also stars Aditi Rao Hydari, Lara Dutta and Rahul Bhatt. "Fitoor" will hit the theatres on February 12.
