Always like going to Gusto salon - the hairdressers are helpful and the ambiance is lovely and hip. Good value for money, it's definitely in my top salon list!
I wanted to lighten my slightly longer than shoulder length hair to a warm chestnut brown and walked out with a colour that was almost ginger. They charged me an extra £70 as apparently my mid length hair was classed as long, and they needed to use a pretreatment but never allowed me to buy the treatment off Treatwell. I think they over sell their ability on their website and whilst they may have worked with some big celebrity names, it was probably 10+ yrs ago as their styling feels dated.
