I had been there 4 years ago and had a bad experience but thought that it might be a one off and booked.
This time the stylist was rude and insisted that I only answer questions that she would ask because she would not answer my questions. She said that if I wanted answers to my questions, I should come to the course that she offers. She would also not accept that she was pulling on the hair and insisted that she knew what she was doing.
I don't recommend it at all.
