Mastey de Paris is a manufacturer of professional hair products located in Valencia California. I worked for the company for several years but had to leave my position because of a consciousness objection to their predatory tactics, particularly regarding their Teinture hair color product.
During the time I was working for the company, Teinture was launched. In many meetings we were told that we were by no means ever allowed to admit to the public that the Teinture included very high amounts of Diethanolamine (a much more toxic and carcinogenic form of methanolamine or MEA), p-phenylenediamine (PPDs), and trace amounts of ammonia. The company, especially Henri Mastey, was committed to marketing the product as the worlds first Zero-Ammonia, PPD and MEA free hair color. Unfortunately, their greed for profit drove them to create a dangerous product that will most certainly cause accumulated liver toxicity, cancer, corneal necrosis, and severe irreparable respiratory damage. [continued below]....
The company adopted a policy of not releasing the ingredients for the product or printing an ingredients label on the bottle. In marketing and promotional materials, they are misleading but arguable truthful. For example:
1. The product is marketed as Zero Ammonia (it actually has 0.9% ammonia and combined with a very dangerous chemical derivative of ammonia). They further explained that other companied who claimed their products were ammonia-free really did have ammonia but since they said that they were Zero Ammonia that they were more ammonia pure.
2. Based on the same logic as above, they further described the product as being PPD Free. The product does actually have varying amounts of PPD depending on the specific color, but in most cases it is much higher than you would find in any other comparable professional hair color product. In the companys logic, once they communicated that the word Free didnt really mean anything; they were open to call anything Free even if the ingredients did exist in the product. I am certain this will not hold up well in court as the countless product liability lawsuits most certainly will start to flow in soon.
3. The company maintains it has no MEAs in the product. What they do not tell you is that it is loaded full of DEAs. Monoethanoline is an organic compound with a very low toxicity but a very Alkali property. Since something was needed to compensate for the low amounts of ammonia in the product, they decided to use diethanolamine which is derived by compounding monoethanoline with ethylene oxide.
4. They knew that anyone who understood hair color would know that some element would have to be introduced to compensate for the Zero ammonia. They came up with a cute name Amino-organic and said that the dangerous diethanolamine is actually the aminorganic a proprietary amino acid akali that acted as a gentle ammonia replacement and an oxi-oxidant. If you are a chemist, you might be laughing right now. But, I kid you not, this is how it is marketed like to this day!
Based on their marketing strategy as described above, they created a very dangerous product. Here is why:
1. Many people are allergic to ammonia and the reactions to exposure could be quite serious and even deadly. Not disclosing the small amount of ammonia in this product is irresponsible and negligent. A clientele of a salon, who is allergic to ammonia, can have 5 6 colors before reacting because the color was left on longer than normal. Risking a life threatening allergic reaction for someone I dont know in order to make more money was not something I could sign off on.
2. I personally understand allergies to PPDs as I have been allergic to PPDs for several years. I carry around an adrenaline pen and have had to use it on a couple of occasions. A PPD allergic reaction is almost always life threatening. To claim that your product is PPD free, knowing that it is loaded with them, is simply inexcusable. Many women hunt for PPD hair color and go out of their way to use them because they are les to believe they are safe. In this case they are not.
3. The introduction of diethanolamine is the most dangerous crime. To avoid having to disclose that MEA (a very safe and gentle organic compound), the treated the MEA with ethylene oxide and created diehanolamine. The product has a high volume of diethanolamine in it. When diethanolamine is exposed to things like high heat or an acid (as in the case while coloring hair), it will convert into nitrosamine. Nitrosamine are highly toxic and carcinogenic well known to cause accumulated liver toxicity, several types of cancer; irritation of the eyes, skin, nose, throat; eye burns, corneal necrosis, skin burns, eye lacrimation, and subtle but periodic coughing, sneezing.
About a year after launch we began to field phone calls from salons using our products who always seemed to have employees who were regularly ill. Then, I learned that 5 hairdressers had been diagnosed with cancer and it seemed that the general health of our clients was quickly deteriorating. We never did give a true ingredients list to anyone even though we always said it was provided upon request. I would like to give it to you now. It is actually quite short:
Partial Ingredients List
Ammonia - close to 1%
Dethanolamine - excessively high volumes
God bless anyone who was had any exposure to these products. I feel so guilty for not taking a stand before. This is the first place I am posting on this. I think my guilt may take the best of me soon and create more awareness.
