Is Mastey Hair Color made with Ammonia or Diethanolamine (DEA)?

No Mastey Hair Color is made with Mono Ethanolamine (MEA) and Aminomethyl Propanol (AMP). We use these two ingredients in varying amounts depending on the hair color shade instead of ammonia.

Learn more about how we use MEA and AMP instead of Ammonia

How long have you made a no ammonia hair color?

Mastey launched Teinture No Ammonia Hair Color in 1982. Over 30 years before it became fashionable. Today many mainstream brands are introducing no ammonia hair colors, but we feel we have a 30 year head start on them. We are also very proud to have the best no ammonia and no PPD hair color in the professional beauty industry.

I read a report at an online website that said bad things about your product, are they true?

No the report you are referring to is completely false and posted by one of our competitors. If any of the report were true we would not be able to sell our products internationally, as all exports are independently inspected and analyzed by the importing countries Ministry of Health or Departments similar to our FDA.

Google search has a number of posts that talk about this report web site as not only a scam but a way to extort money from the companies that are posted there.

Why don't you get the report removed?

Unfortunately the law protects the web site from being sued because the report and comments are made by anonymous or fake screen names, so there is no real person behind any of the negative comments or the original report. You can read more about why these anonymous sites can't be prosecuted and how they make their money by visiting the links below.

How do you know it was a competitor that posted the report and comments?

On the same day that this report was posted a large number of hair salons across the United States that had previously used a particular “Organic” hair color and had recently switched to Mastey Hair Color, all received negative reviews from the same screen name on Google Local Reviews citing this report. We were able to show Google Local (Maps) that there was NO WAY that 1 person could have traveled to this many salons in 1 day across thousands of miles and had their hair colored at all of them. So Google saw this as FALSE and as SPAM and took those negative reviews down and shut off the spammers account.

Salons have also received emails and phone calls citing this report only to then be pitched on switching to this other color line.

Does your product have p-Phenylenediamine (PPD)?

No we do not use p-Phenylenediamine in our hair color. We use a combination of oxydative dyes and you can see a list of all of them on our hair color ingredients page.

What do you use instead of PPD and why?

We use an ingredient: toluene, 2-5,diamine sulfate instead of p-Phenylenediamine in mastey hair color. We use this ingredient because we believe it is less irritating than the alternative PPD. Both the U.S. Cosmetic Industry Review and the European Union's Scientific Committee on Consumer Safety agree that Toluene, 2-5,diamine sulfate has the lower reaction percentage compared to p-Phenylenediamine (PPD).

Visit the reports for the EU Committee show toluene 2-5 diamine sulfate as being 2.5 to 5 times less irritating than p-Phenylenediamine (PPD).

Is your hair color organic?

No but neither is any other professional hair color unless it displays the USDA symbol for organic products, proving that at least 70% of the ingredients are organic. No professional hair color company currently has that certification, not even if they put the word ORGANIC in the name of their company or the name of their brand of color. We believe that color companies that are marketing their color as "Organic" are knowingly deceiving the stylist and the consumer. You can read about the USDA requirements or the CA State Requirements on Organic Products at their respective web sites.

Do you use amino acids in your hair color?

Yes we use gluten-free rice amino acids in Mastey Hair Color to help repair and protect the hair while it processes. We also use vegan moisturizers derived from vegetables to help maintain proper moisture levels. As well we use Grape Seed Extract to help prolong the life of your hair color

Does your product use Fragrance? Why and what kind?

Yes, Mastey hair color uses a blend of essential oils and synthetic fragrances. All the ingredients in the blend are certified Phthalate-free. We work closely with our fragrance provider to make sure that we have a pleasant yet non-irritating fragrance for all of our products.

Should you still perform a patch test on people that say they are allergic to color or certain color ingredients?

Yes, absolutely. The reason for this is that many people are diagnosed with a hair color allergy from their hair stylist and not from a physician. Stylists should always perform a patch test on these customers to make sure they aren't allergic to something else. For high sensitivity clients you can perform a patch test a week in advance of their service to make sure they do not have any type of reaction.

Do you have a lot of allergy incidents with Mastey hair color?

No we actually have a very low incident of allergies because of the ingredients that we use.

Do you get calls from stylists that cannot use other hair colors anymore that want to try Mastey?

Yes we get calls everyday from stylists that were using other color lines and developed mild to severe allergic reactions or have developed contact dermatitis. We are happy to help these stylists by providing free hair color samples for them to try, so they can see if Mastey is a solution for them. We recommend stylists with allergies or contact dermatitis patch test themselves before using any hair color.

We are very proud that we can help many stylists to continue their career while using Mastey hair color as a gentler alternative to what they were using before.

What other gentler types of products have you made?

We created the first sulfate free shampoo and have sold it since 1978. Over 30 years later no-sulfate shampoos have become the standard and we are proud to have led the way in their development.
