What does a gel cast mean? I have heard many people talk about it.
It's the protective coating that forms around your curls while they're drying. When a gel is applied properly, the gel cast should keep your curls from getting super frizzy. After your hair is completely dry, it is best to "scrunch the crunch" out of your hair (or break the gel cast) so that your hair doesn't look stiff and crunchy. Hope that makes sense :).
