I couldn't believe how knowledgeable and well-informed the staff was. They were able to answer all my questions, except the ones they needed to have their boss's input on. It was great to be able to talk to such a skilled staff. My stylist made an extra effort to make sure I wasn't sprayed with water. I was extremely impressed. I always have a lot of questions, but they were able to answer every single one of them thoroughly, and clearly. They are definitely experts.
