Sadly, I did not get a photo. I was on the phone with a church member and in so much shock I was even having trouble speaking! I did a vinegar rinse this morning and then another wash with Dawn. That seems to have helped. It feels like what is leftover is the zinc part of the sunscreen. I think in a day or so I'll do another vinegar wash and then just a clarifying shampoo and it should be ok.
Thanks for everyone's suggestions and stories. I definitely had a few chuckles.
