Ladies, I find that some conditioners can be chelating, as well.
I have hard water and some deep conditioners with EDTA in them have been just as good, when I don't want to use a clarifying shampoo for the job.
I find that I use my Kenra Chelating much less often.
Also, I look for chelating ingredients in moisturizing shampoos.
The shampoo DOES NOT have to say it is chelating, in order for you to get the benefits of chelation. Just check the ingredients.
