I have silk sleep caps and a silk pillowcase, lol. I usually have great curls in the morning--a little flat, but I can fluff them up pretty well. I think silk really helps to minimize frizz, but some of it was just figuring out product and how much to use. I had some really bad days before I developed a decent routine.
