The fight erupted earlier this week when a woman became upset with the pricing charged by Regal Nails near Snellville, then spent 30 minutes swearing at workers and other customers, WSB-TV, Atlanta, reported Tuesday.
As of late Tuesday, police still were searching for the woman, who fled.
The fracas broke out after the woman's children clashed with the child of another customer, witnesses said.
"And from there, it was off the chain," a witness told WSB-TV, Atlanta. "Bowls were flying, glass was flying, hair was flying, braids was flying, weaves was flying, everything was flying."
A porcelain soaking bowl struck Ashley Corbett, 17, in the face as she waited to get her nails done.
"As I headed toward her, all I could see was just blood," Corbett's mother, Gail Dudley, told WSB-TV. "She opened her mouth and her teeth were shattered."
"I had nothing to do with it," the daughter said.
