When I was solely using products with glycerin my hair felt great and I did not experience splits. My attempt to move away from products with glycerin has not been successful. I have not had any issue using the Deva Curl products this summer. I saw that article. I'm not a scientist but it seems a little crazy. So you can't use glycerin in the summer because of dew point and humidity. And then of course people don't want to use it in the winter because of the dry air. Some people's hair just doesn't like glycerine. If you know your hair doesn't like glycerin then try something else. But if you have done fine with it in other products, I wouldn't shy away from it.
