Keratin Formaldehyde Side Effects - The Truth
I have been a hair stylist for 11 years and I have been doing the BKT for over 3 years. I have used formula's that contain formaldehyde such as Marcia and Lasio. I can tell you after a lot of research and personal experience, that if you have to leave the product in your hair for it to work, it does contain some form of formaldehyde.
There are many sister aldehydes of formaldehyde and the chances are they are using one of those. If you are feeling any type of burning in your eyes, nose or throat, there is something wrong.
I have experienced hair loss in some areas of my head from having the treatment done and the hair has never grown back. I think that some hair stylist are fooling themselves into believing there are no health risks, because of the great results they are having with the treatment. I too, loved my hair with the treatment.
If you have experienced any side effects from the treatment, something is wrong! Wake up people, formaldehyde is a carcinogenic, which means, it causes CANCER! Sides effects of formaldehyde include... burning of eyes, nose and throat, dizziness, shortness of breath...I can go on. You can find all of this information online, if you just look for it.
If a salon claims their product contains no formaldehyde and then also says you have to leave it in for x amount of days, for it to set... RUN! If you have to wear a mask or sit outside while getting the treatment, something is wrong! Trust your instincts! Those of you that are hair stylist pushing this treatment, I suggest you do some research and educate yourselves.
Yes, there is formaldehyde around us and we are exposed to it day to day. The problem with the BKT is, that when you are heating it up with the flat iron, you are fumigating the formaldehyde and breathing it in. That is what is dangerous about it. It doesn't matter if it only contains a small amount. There are no studies about the long term effects of this, so you are taking a chance and playing with your health.
I urge you all to do your research and don't fall back on the excuse that it is just a competitor trying to fool you.
