I started going to Tonic II because of a Groupon and good things I've heard from a lot of people. I will continue to go there because it's overall a fantastic experience everytime from start to finish. The receptionist is always pleasant and offers you water (or wine!) as soon as you walk in. The layout is nice and organized with huge mirrors at every station.
Amy is my stylist and does a great cut and color. She is really nice and relatable so the two hour service is pretty relaxing as opposed to a necessary evil every other month. As a picky hair person that knows what I like, I sometimes ask her to make adjustments and she happily does it until my obsessive compulsive heart is content. The price is reasonable and pretty standard for most salons in Las Vegas except unlike other salons, it's guaranteed to be a great experience with the end result of great hair.
