Hands down the best in Chicago (and one of the top ones I've ever been to!). The color looks phenomenal and lasts at least a week. Even when the color starts washing off, it's not blotchy or streaky.
I get a lot of compliments and notice that the color looks great in pictures.
Finally, the staff is super friendly and very courteous. They always work with you if there is a problem and have never let me down. They also make the airbrush process very comfortable!
