Faye Dunaway caused a big drama at celebrity favorite Marie Robinson Salon in Manhattan after racking up a $3,000 bill for extensions to her tousled locks — complaining about the price and storming off in a huff.

“She claimed she didn’t know it was that expensive and then said, ‘I’m not paying that. I can’t believe how expensive this is. I’m only paying half!’” a source exclusively told Page Six.

Finally, “they took her half, but staff explained, ‘You’re going to have to pay the rest.’ And Faye stormed out screeching, ‘This is ridiculous!’ Everyone in the salon was aghast … Her hair looked great — so she should pay!”

A source close to Dunaway told us that the Hollywood legend had gotten the extensions on a previous visit to the salon, and that this appointment was made for touch-ups. But instead of charging just for touch-ups, they charged her the full fee again.

When we reached out to Dunaway about the hair-raising incident, the star said, “I’d prefer you not run that. I’ve now paid the whole thing — but I will not be going back there because it is not the price they said it would be. So, I don’t know what to say to you except I didn’t throw a fit. I was just very alarmed at the amount they were charging me for the very small amount of hair work that they did.” She continued of the coiffure calamity, “I am a normal human being and don’t expect special favors, but I was shocked to be charged the same [fee] I had previously paid to get what was now a hair correction. I felt it was extravagant and inappropriate.”

A receptionist at the salon told us, “There’s no one here who can comment on that right now,” and salon staff didn’t return emails. Fusion hair extensions, made from real hair, usually cost well over $2,000 in NYC salons.

Dunaway was famously kicked out of her NYC rent-stabilized apartment, where she paid just over $1,000 a month, in 2011 after the landlord sued to evict her. She also made headlines earlier this year at the Oscars as a presenter with Warren Beatty when she announced the wrong Best Picture winner.
