I have been to Gusto several times for a wash and blow dry and am never disappointed. I ususally have a different hair dresser every time - but each one has been extrememly nice and willing to style my hair as I ask them to. The salon is small but very efficiently managed.
Avoid at all costs. My hair has been ruined!! Booked an appointment, had to wait 35 minutes before being seated so I guess they were trying to make up time, in turn bleached by hair, ruined the condition, and was left with streaky yellow racoon looking highlights. The price is too good to be true, as it will ruin your hair.
It is always a little concerning when you try somewhere new for the first time but I needn't have worried. The staff were friendly and Ilonas, my hairdresser, really listened to what I wanted. I came out there with probably one of the best cut and colours I have ever had, I would highly recommend it to anyone. The only possible negative is that it is extremely busy so if you prefer your salons to be quiet, ambient and relaxing, this is most likely not for you.
Carmel did an excellent job on half head of highlights, wash, cut and blowdry. She fixed the dodgy coppery colours left over from the last hairdresser I had gone to. I have found a hairdresser in London worth going to!
