I have had a dozen of these treatments and this one was top notch. It is the one that requires 3 day without washing but after having a same day treatment, I wanted to go back to this method as it suits my hair better. A lady called Tsegy did it and she did not miss a strand and was very thorough. For a treatment of this standard in a more upmarket salon you would expect to pay well over £200.
The salon had a buzz about the place but not what I would call relaxing. It was great that I could get a last minute appointment on the weekend, but when I arrived my hairdresser spoke little English. Luckily this turned out not to be an issue as I only had a trim - I'm not sure I'd be so comfortable with colour and/or a restyle with this language barrier. That said, I had a great blow dry!
Would probably return for a wash and blow dry or recommend for a men's cut but overall value for the money in central London.
