I would never perform a Keratin Smoothing Treatment without the Chemical Source Capture System. I am confident that my clients are being protected from any harmful vapors or fumes that are being given off when performing keratin based treatments with high heat. Prior to having the system, I was well aware that the formaldehyde content was high. My clients still wanted the treatment so they had to suffer through burning eyes and itchy throats. I was ready to give up performing the treatments altogether. I have had the system in my salon since September 2010 and have had many referrals due to the fact that I have the Chemical Source Capture System in place. All my clients and co-workers have commented on how great the system is. It removes any vapors in the air. Our salon never smells like a salon. The Three Zone Protection system truly improves the quality of the air in the salon environment. We’re very happy. Thanks!!!
