My hair stylist was fantastic, he provided very honest feedback on my current style and recommended new styles which may suit me better. He was very thorough with his foils (I used to work at a hair salon so can find myself to be pretty fussy especially with how blonde my hair currently is) and also put a lot of work into the blow dry and styling.
Only constructive feedback I have is that the 'osmo' treatment was very short - Possibly suggest leaving it on for longer in future.
I couldn't recommend this place more highly - the service and the haircut were incredibly good value for money (even without the discount). Ionas asked what I wanted, talked to me about how to improve it, then gave me a great cut and showed me how to style it at home. Everyone was very helpful and friendly; the whole place was great. It was small, and not the same as a designer salon, but I would definitely go back.
