I just bought Nairobi Detoxifying Shampoo. It says it gets rid of chlorine, minerals, medications, etc... I haven't used it yet but I hope it's good. I've tried others (IT & LY Chelating and Mizani Neutralizing/Chelating and a few other shampoos) and they all had polyquats or silicones in them. While they made my hair feel nice, I didn't want things depositing back on them when I was trying to take everything off. That's why I like this Nairobi one - it doesn't have any silicones or anything in it. They don't call it chelating though, just detoxifying.
