I went to this brow bar on Thurday March 6, 2014.  I wanted my eyebrows cleaned up.  I had also asked that my eyebrows be filled in.  When I returned to my hotel room, I noticed that a chunk of my left eyebrow was missing.   I wondered why the woman who waxed my eyebrows gave me a $10 tube of mascara for free.    I have gone to the Benefit Brow Bar at the Macys in downtown San Francisco, and the Benefit Brow Bar at Bloomingdale's in Manhattan.  I have never left with a chunk of hair missing from one of my eyebrows.
