Lauren Newton, 28, was getting her hair cut Thursday at the home of Monique Reed when the two began to argue about the style, police said.
"She (Reed) went to the bedroom, got a gun, fired a shot in the ceiling," Police Chief James Blyth said. Newton, who was trying to flee with her sister, was then shot in the lower back, he said.
Reed, 38, was charged with aggravated assault and reckless endangerment. She remained in jail in this southwestern Pennsylvania town in lieu of $50,000 bond.
Newton's injuries were not considered life threatening. She was taken to a hospital in nearby Pittsburgh for treatment.
The district magistrate's office said Reed had not listed an attorney as of late Thursday.
