I don't even know where to start with this. If you bought the groupon or are considering buying it and checking out the reviews to help you decide... DO NOT BUY IT. My friend did the exact same thing. The day of her appt she was looking at the reviews second guessing herself but decided to go anyways.
She had an appointment with Kim. She bought a coupon through groupons sister company. She showed up and Kim acted extremely unprofessional, swearing and telling her that's not her, she is not associated with that website and someone is impersonating her. Another worker in the salon had to step in and continuously tell her to calm down because she was making a huge scene in the middle of the salon. It was handled very unprofessionally, and in the end it turns out that she did have a deal on that website. I felt bad for the worker who stepped in to help as Kim was very rude to her as well. That should have been red flag #1
We then went upstairs and Kim seemed to know what she was talking about. My friend grew out her highlights and Kim said she would draw the highlights up a bit to soften the contrast where it grew out while also highlighting a bit of the bottom as well.
She didn't consult my friend anymore about what she was doing and dived right in to doing her hair. She painted thick streaks throughout her hair and then toned it. She then dried it and attempted to style still wet hair with a curling iron. The hair that grew out that my friend wanted some highlights added to was all copper/orange! She didn't use bleach which she should have but instead she used hair dye!!!! ( the dye was white not blue which is the colour bleach is)
