  1. Thank you for the info. I have been using mayraki keratin on myself and clients for a few years now. The directions of use have changed in the past year and now require you to blow dry and then iron hair without rinsing first. I always rinsed out in the past, but tried it for the first time the new way and I noticed immediately a lot of smoking and my throat burned. The following four days I became worse and day five brought a terrible burning cough and sinus infection I had a chest x ray taken and the dr said abnormal results with two shadows on right lung. I am now on steroids and antibiotics and an inhaler with a diagnosis of a chemical burn to my throat and lungs.i was fine before I preformed the treatment and dr says this is a result from the keratin. Needless to say, I will no longer offer that service in my salon.I believed the product was chemical free and safe. Clearly I was wrong. I came across your article while up coughing and throat burning and figured I’d research as I couldn’t sleep.wish I had researched better sooner.

  2. Cyclopentasiloxane is the first ingredient in Trader Joe’s Antioxidant Facial Serum. I have been using it recently as part of my daily regimen and am really glad I found your article!

  3. Hi Irina, happy new year! Do you know if silicone creams and patches for scar healing also have endocrine disruptors? I’ve been using 2 products (ScarAway and BioCorneum) for scar treatment post-surgery, with silicone being “the #1 scar treatment recommended by doctors”…. now I’m curious if there may be some unwanted side effects I wasn’t aware of. 🙁
