Horrible! My hair was so bad and it was very overpriced. $130 for a root application with single process colour with a junior stylist.
The lighting in there is so dim that even the stylist can't properly see the colour, which became painfully obvious when I returned home and into natural light. I've never had someone mess up my hair so badly. He applied level 6 (or so he claims) Wella colour to red hair. I had black roots and copper ends.
I had to go elsewhere for a $230 colour correction, and then pay for once more before my hair was finally looking decent again. But because he used permanent colour, my colour will never be the same until it grows out.
Even the President of the company where I work made a comment about how bad my hair looked - and I didn't think he knew I existed.
Stay away!
