Not a hairdresser, but I was a client at a salon once when a woman came in for a consultation. Her hair was in terrible shape (overprocessed) but she insisted on another colour or perm. The hairdresser refused to colour or perm her hair but the woman would not have it. The woman really caused a fuss but the hairdresser held her stand. I'm afraid this woman would not have been pleased no matter what was done to her hair.
