/images/graemlins/wave.gif I know we're trying to put this one to bed, but I wanted to let you all know about my conversation with the Straigh Arrow company today (makers of Mane N Tail)...
I spoke with Diane in Consumer Affairs for Mane N Tail. They do know about the article in Forbes and have confirmed that MIT is only in the Deep Moisturizing shampoo. It was also in the regular shampoo several years ago, but they stopped adding it a long time ago.
Diane has spoken with one of their onsite chemists, as well as the company that tests their product line (CIR), and they have all confirmed that the levels of MIT are not harmful enough to cause brain damage. Additionally, since you are rinsing the shampoo out of your hair, the chances are even slimmer that it could be harmful.
This may or may not be the case with other brands, but you'd have to check them out to be sure.
I'm sure they'll release a statement at some point because of all of this.
Thanks,
SG
