Ok maybe it is not that magical but I started sleeping on a 100% wool sweater and it really does seem to do something for the hair. I had always heard to wear a wool tam but I don't have one and most of the time it is too hot for one in the south (in my opinion) but had never thought of sleeping on wool. This is a good compromise. Plus if you toss and turn like I do your hair is getting rubbed all over the wool more so than just wearing a tam for a few hours, at least *I think so.
Thanks to the folks who suggested this.
