This is a great shot, one of the best in the challenge IMO. Everything works from the reflected car that draws the eye in, to the interchange between hairdresser and client and the poster to the right.
It brings back memories of my few trips to the hairdresser (I hate going). they start by asking who cuts your hair, then they ask where you're going on holiday, and all the time you're thinking to yourself that you hope that chattering inanely doesn't distract them from the job.
You've captured it all so well.
Flick.
