Cavenia Bryant entered a not guilty plea to two misdemeanor charges of battery and false imprisonment for the 5-minute attack on Melissa Seals.
Police say Bryant and another woman, Jaymillya Edgerton, ganged up on her, punched her, kicked her, and prevented her from leaving.
A warrant is out for Edgerton, but she has not been arrested.
The salon owner says she is surprised Bryant pleaded not guilty since the entire attack was caught on video.
"You have a videotape. I don't have to get on the stand and testify, you know, against her," said Seals. "Her own friend taped it."
Bryant will be back in court next month for a pretrial hearing.
