Hillary Clinton put part of Bergdorf Goodman on lockdown on Friday to get a $600 haircut at the swanky John Barrett Salon.

Clinton, with a huge entourage in tow, was spotted being ushered through a side entrance of the Fifth Avenue store on Friday.

A source said, “Staff closed off one side of Bergdorf’s so Hillary could come in privately to get her hair done. An elevator bank was shut down so she could ride up alone, and then she was styled in a private area of the salon. Other customers didn’t get a glimpse. Hillary was later seen with a new feathered hairdo.”
