I unfortunately had a bad experience when I went for a color. The color didn't turn out quite like I would have liked and washed out within 2 weeks. I got a demi-permanent because I have curly hair but the colors I've had before lasted at least 6 weeks. The stylist agreed to redo it but gave the job to an assistant. When I came home my husband told me I had a big dark brown stain on the back of my dress, and when I woke up the next day, my white pillowcase was brown! The salon has been very understanding though and reimbursed me, but I'm not sure I want to go back there now!
Also, both stylist and the assistant couldn't style my hair after the color. I had never looked so disheveled in my life!
