My go-to salon for years now.
I travel all over for work, and I usually will wait until I get back to Phoenix for a hair service. The service is always on-point. They have free champagne! They have fun little after-hours classes and deals going on all the time.
They do their best to make sure you're happy. Out of all my visits, I've only had one hair service where the results were less than desired and they tried their best to fix it. I believe you have 14 days to love your hair? At least that's how long I had to see if the color treatment I received would show.
Anywho, the one bad experience hasn't deterred me from this salon. I think it still has the most comfortable hair washing stations, and the staff is knowledgeable.
