I can fix hair not crazy.

A new client came to see about getting her roots done. I've never seen her before. She was quite friendly and  very chatty. I thought that we were becoming good friends. Until she started to spill her guts to me. Her problems with her Ex and her old hairdresser. That made me nervous, I don't like to  bash other colleagues that I don't even know. Yet, I had to emphatise with her. She told me she wanted fine weave hilites and refresh the dark underneath from the back. She wanted 3-4 in of hair cut from the back . We picked the color for the bottom and we both agreed. I cut,colored,toned and styled in 3hrs. It looked gorgeous. The color was amazing. She hugged me and tipped me. A job well done. The next day, I get a text from her cousin who comes to the salon regularly. " She hates her hair!" She can still see her roots!" "Her color application was sloppy!" So I called the new client, and asked her what can I do to fix this? She agreed to come down on my dayoff to fix the misstake she claimed I made on her hair. She was apologetic. I told her if your not happy,I will fix it. She agreed. And she asked me if she was being too picky. I said."No." "I would like to see it and I will accomodate you. " Five minutes later, she called and booked with someone else at the salon.
