Formaldehyde-free Keratin Products Are Carcinogens
(Miami, US)
I am a stylist in Miami who has used numerous different brands/formulas of the "Brazilian" Keratin Treatment. To tell you the truth, I (and my co-workers) have concluded that there is no perfect Keratin Treatment.
The original formaldehyde formulas were by far the best as far as straightening/de-frizzing. Period. The lower formaldehyde formulas were not as straight & didn't last as long. The Coppola Complex & other formaldehyde-free products that our salon tried were the least straight and didn't last very long. I question the person who commented claiming it lasted 8 months. Our clients were very unhappy with CKC.
The problem is toxicity. The original formulas were highly toxic (didn't take a scientist to tell us that the fumes were not healthy to breathe) and removing the formaldehyde clearly changes the results. We also did our homework & most form-free products, including the Coppola have other ingredients with are similar and are also toxic. Coppola uses Aldehyde and another product uses Ether (Global Keratin). Both ingredients are carcinogens when heat is added.
The results from these treatments appear to make the hair healthier. but in all honesty, as a stylist performing these treatments I have not seen hair become healthier after multiple treatments. I have been performing these on clients for over 2 years & I have not seen any major difference in my clients hair, it just appears healthier because it is coated with this product. If anything I think it possibly becomes dependent on having the treatment to look healthy.
My advice: get good styling products & a quality brush/ dryer/ iron.
Hi ,i started to have Coppola keratin complex in 2009 -it left my hair straight- no need for blow dry or irons etc...the only down side was the fumes and stingy eyes.
Hi everybody, Im a hairdresser as well as a product developer for manufacturers for over 20 years now. First, there is no such thing as Formaldehyde-Free Keratin, simply because it wouldn't work! Its just BS and its quite dangerous for the health for the techs and hairdressers using it especially if there is lot of demand. The concept itself is great, because once in a while salons need new services to attract clients and a boost to the industry as well. Its just the formulation that really needs to refine! Sometimes company would just launch the product just to make money until something happens! Did anybody notice the little flakes when you clamp the Coppola keratin? Its really cheap silicon!!!! Hopefully, we will have a safer product that produces same result soon! Keep your fingers cross!
I just want to thank you for this post! I have commented on this blog a few times trying to help these women. I have cut and paste many articles I have found warning of the dangers of these products and tried to put as much info on this blog as I can find just to help inform stylists that don't do research and women thinking of getting these treatments. 
Thank you for the continued updates the honesty in your review and information is very refreshing in this sales driven education lacking industry! 
Thank you for your honest comments. Shame that such a good resulting treatment is soooooo bad for us...
As a stylist an educator or who has been trying to find information on the Brazilian Blow dry Keratin System. Thank you for the honest review. So many products are misleading and do not provide professional with all the information required to make good choices.
I also work in a salon as an assistant and i believe we use the Coppola keratin treatment. many of the stylists a couple of clients and myself have all complained about the fumes that come off while blow drying and straightening the hair. Now i know why. The only thing/ reason i question what has been said here is because of the fact that a demonstrator for the product actually ate some of it too prove it is all natural and not harmful....is this only true in the liquid state??
Yr awesome....great to hear from a hair designer! I have been doing the beox one and have looked into all of them ...but i feel like my throat hurts after the treatment! Now i know im not crazy!
Really thanks for your honesty, which i think all people who read your comment had appreciated your view, really many thanks...
