I love the girls over at Grooming Humans! Everyone is super nice and friendly, and that's saying something because I'm usually intimidated by salons.
The first time I went, I had Holli give me an all-over color. The second time, I had Kate put in some low-lights to hide my roots as well as a cut. Both of them did great jobs, and didn't mind accommodating me when I was worried about the hair dye getting on my new ear piercings (just ask them to put a bandage or something over it; they'll also be careful around that area).
Before I went to Grooming Humans, I was a $20 haircut type of girl--but I can really tell that difference in quality between a $20 cut and a cut from Grooming Humans... and I'm addicted! My hair looks tons better after they're done with it. Plus, it's literally across the street from ASU's Tempe campus! Score!
