I don’t have color treated hair and ordered the wrong shampoo. You can see I have ordered twice in my emails. I film inspection, packing, and shipping while at the post office to avoid fraudulent returns. These are unopened. The 0 is sealed outside, and the 4P shampoos are sealed in the lid. I cannot open the lid to show the seal because I’m afraid to break it, however you can see it through the nozzle.
