I remember walking through there a couple of times back in the 70s. My mate used to go there to get his hair cut. I seem to remember it was lined with various shops, the hairdresser being one of them. Maybe the hairdressers was at the beginning of the passage on the Kendals side and my brain is embellishing the rest, I don't know it was a long time ago, but the hairdressers was definitely there.
