I enjoyed reading this article very much and I am wondering are you familiar with a product called Mastey Teinture Zero Ammonia, No MEA, Hair Color? I had been vacilating between using this color line and the Organic Color Systems. I had more recently been leaning toward using the Mastey Teinture but then I saw some alarming information about Mastey Teinture using highly carcinogenic DEA in their products and not disclosing it. I was wondering if this claim was true or some sort of hoax because this product is marketed as being more gentle than even the Organic Color systems line. Are you famiiar with this product or with these new claims? They have been posted on a few websites and threads by a John Bailey under the title “Mastey is Nastey”I would appreciate your thoughts or any research you may have.
