I've finally got my hands on a bottle of Glycerin. I always let my finger coils air dry when I do them. I've noticed that the top of my hair (which is the thickest part) would always stay a little moist. If the humidity was high outside, my coils would be damp. I thought it was the Glycerin in the Eco Styler gel. Curly Nikki confirmed it :-) The article explains that Glycerin attains moisture from the air. That's too cool :-)
I mixed Glycerin with water and applied it to my hair. I'm pleased with results.
