Every shampoo I’ve bought since I first noticed it. Most notably, two different formulas of Suave Daily Clarifying. I also remember a Target knockoff of Pantene had it and a current bottle of TresSomme has it. My current bottle of Ivory dishwashing has it and a couple other brands that I don’t remember had it. That’s what I remember off the top of my head.
Different kinds of plastic bottles – some clear, some colored.
