I've seen Allison twice at this new salon in Scottsdale. The space is a little hard to find tucked in between home design storefronts in a new complex on the G/Hayden Loop. Staff is friendly and welcomes you with a beverage of your choice. The AC is always on full blast or something as I am always a little chilly - bring a sweater!
I moved here 6 months ago from San Francisco where I had seen the same stylist for years so forming a new relationship has been scary. They seem to consistently run a bit late for your appointment - both times I had to wait 15 or 20 minutes after my scheduled start time which is a little frustrating. I've been generally happy with my "do" both times though. The first time my color faded fast, so on the second visit Allsion suggested a different approach using a blend of permanent and semi to try to extend the color. They also carry Kerastase products which I love and are kind of hard to find. I haven't tried any of their other services as of yet, to me it doesn't feel "spa like" so I forget they have other things too.
