I've been to this place a few times and had a different hairdresser than I would have booked and unfortunately I did not have a good haircut here. Even though you choose from a menu before you book online, the person who cut my hair did not seem to know how to cut short hair or know how to fade properly... to their credit, they consistently checked with me with the mirror to see I was happy with it but I ended up getting sick of it. To be honest, I've had a better free haircut at the London barberschool. £40 is significantly overpriced for the haircut that I received.
When the hairdresser felt like they had finished I had to correct them multiple times as the hair was uneven.
I don't want to name the hairdresser as they may be better at cutting women's hair and looking around, there clearly are hairdressers there who know how to cut short hair. It should be up to the owner to ensure consistency or that their hairdressers are trained for all styles or know to ask for advice. Its a £40 haircut...
