It has taken me a while and lots of heartache and trips to the dermatologist to find this out.
I stumbled on it actually because I noticed that after I used Kenra Clarifying, my hair would instantly improve. If I use some other clarifying, say Keracare, which is not chelating, my hair went back to misbehaving. That may be why Keracare has the wipes. Their clarifying does not have a chelating agent in it.
My facial cleanser is even chelating. My skin improved 100% and my hair is going very well.
I think some ladies get calcium buildup from no-lye relaxers, as well. These wipes can be used for that, too.
