I feel that moderator Carey Gregory ♦ deleted my answer for no reason.
I tried to answer the best I know.
Please, can this moderator behavior be verified?
I have a bad feeling about censorship and hindering free research in this group, which should not be in conjunction with StackOverflow.com
I flagged your answer as low-quality, which is probably what drew moderator attention to it though they likely would have made the decision themselves.
Your answer was not an answer according to the standards of this site. See some relevant meta posts:
Your answer was not referenced and based on anecdote and pseudoscience. It was poorly formatted and makes many claims not held to be true by medical science. This is not a site for you to opine about the motives of shampoo manufacturers, it is a site about medical science for professionals, students, and others interested in health-related sciences.
