I am wondering about Ecostylers as well because I just discovered that I can get them pretty easily here in the Netherlands for only 3,95 per 16 oz tub. I've done a lot of research already but it seems that it elongates curls (my wavy wurly hair does absolutely not need that) and that it is particularly 3s and 4s that like it.
