Major hair disaster

I'm overdue for a haircut. WAY overdue. With no end in sight.

I finally called my salon yesterday to make an appointment. And to my horror I was told that Sheridan has left, but that they would be happy to recommend someone else. Sheridan has been cutting my hair since the beginning of the '00s! I don't want them to recommend someone else. I want them to give me her forwarding information. Which, as yet, they won't do. Sheridan gave me her cell phone number years ago, but it is (best case) in my old Rolodex in a box in storage. Any other suggestions on how to find her??? If I cannot, am I doomed to a future of Crystal Gayle's hair???
