The vehicle drove into Nail Sensations at 2980 E. Capitol Expressway just before 10 a.m. No injuries were reported, San Jose fire Capt. Cleo Doss said.
Salon owner Denise Nguyen said she heard a loud noise and thought, "Oh my god, what happened?"
She went outside and saw that a car had backed up into the building from the parking lot, shattering a window and damaging a door.
There were only two employees in the building and no customers at the time of the crash, Nguyen said.
She said early this afternoon that the window had been repaired and the salon was open for business.
