Okay, there is no point in being afraid of something you've already purchased. Second, not all polyquats are the same and lastly a large number of people have no issues with polyquats. Those of us who've had issues come on here to share our experiences in the hopes they may help someone who is having unexplainable problems with their hair...not to scare the living daylights out of people.
Even if you did, simply clarify and don't use them again. It really isn't worth worrying about. I promise.
