I used to buy my pieces from Hair Development many years ago.
Michael was the cutter then. I never had my hair cut there but back then, it was a space at the back of the shop and just before the stock room.
It may have improved by it was like a down market barbers and inspired no confidence.
I'm surprised they're charging £50, but by the sound of it, thats cheap compared to others.

I really think a mobile hairdresser would provide a much better service and be much cheaper.
You could tell them your situation over the phone and they could come to your home.
