I've been using CK under a gel, since June, with really good results. My question is, is this just a summer/humidity product? Or do people generally use this all year round? Do you think it enhances curl formation as well as reduces frizz? I was worried that maybe in the cooler weather it might weigh my fine hair down. Also, how much of this are you supposed to use? Finally, what is your favorite gel to use over this? Thanks.
