Here I am with an update. The same lady I may or may not have converted came back to the store a few days ago. She returned the Revlon straightening iron (yay!) and the hair gel (she said she found an unused bottle under her sink). I don't know whether I've truly converted her or not, but I like to think that I did since she returned the iron. I really hope I did this. If I did, it's probably the first time I've ever made a change for the better in someone's life.
I use the Totally Twisted line from Herbal Essences: Conditioner/gel daily; shampoo and Wella In-Depth treatment once a week.
