The Morrocco Method site is a marketing site trying to sell your their non-selenium shampoo. Just who taught you how to research anything, you bozo? You don't ref advertising literature as though it were a research paper! That's like a girl believing a guy who says "I love you" when he has a stiffy for her.
The other site is a wacko health site (pare back to the base URL to
www.healthy-communications.com and then click on "My Favorite Products" and you'll get snake oil products like "Parasite Purge," which lists wormwood, among other ingredients. Guess what? Wormwood is a poison. Hey! Isn't that what you were saying about SLS in shampoo?
