Below is the lawsuit, captioned Myrella Ikeda v. J. Sisters 57, Inc. et al., 14-cv-3570, recently filed in the Southern District of New York.
According to the complaint:
[Plaintiff] visited J. Sisters with a prominent Brazilian hairdresser and television and magazine reporter as part of a photo-shoot for a well known Brazilian fashion magazine. [Plaintiff] arrived at the salon  anticipating that in a few hours she would have spectacular hair that would help launch a modeling career. But eight hours later, she left the salon with physical and emotional trauma: her scalp and and hair were burned, her modeling plans were in ruins, and she could not show herself publicly. All of this occurred at the incompetent, reckless hands of J. Sisters; its co-owner, Jonice Padilha; and its hair stylist, Antonio Luis Rosa.
She asserts claims for negligence, recklessness, and negligent supervision.
