AMAZING!!! I had Biba for balayage and it is one of the best colours I've ever had, super natural, and didn't skip on the dye even though I have really long hair, and gave great honest advice actually advising me against something that I asked for as she didn't think it would suit me, couldn't recommend more!
The salon is quite cramped, staff are friendly. The cut was pretty bad though - I asked for scissor cut but she kept using razors and my hair is too short in places and weirdly longer in others.
