I was looking at the ingredients in the CHI Enviro American Smoothing System and I'm not understanding how it smooths the hair since it says that no bonds are being broken. It says it's "formulated with amino acids, proteins, silk and pearl. The combining of cysteine can synergize with hair's natural cysteine, thus rearranging cysteine proteins in the hair's natural fiber. There is no bond breaking with this invention, only rearranging." What do they mean by "rearranging"? Is this even possible? And if so, are the ingredients in there to do that? And what is "cysteine"?

 All I found in the ingredients were silicones and keratin (and silk and pearl but I assume those aren't really doing anything). It comes with a sulfate-free shampoo and conditioner and a serum that the client is supposed to use and it says that "the new protein rearrangement can be cured to last for up to 4 months by using the CHI Ceramic Hairstyling Iron set at 410 degrees. Thus sealing and bonding hair to produce smooth, silky, strong and shiny hair."

 So my other question is, how does this keep hair smooth for "up to 4 months" if there aren't any bonds broken? My assumption is that this smoothing system, and probably the rest of them that say they don't break bonds, are just coating the hair with a ton of silicone and it's never being washed off because sulfate-free shampoos won't rid the hair of silicone, right? So, after the 4 month mark, enough hair has grown out that it needs to have silicone coated on it for it to be smooth? Also, the keratin I saw in there is doing what? Smoothing the cuticle down?
