Review (3/5): These run small!  Not recommended for lots of hair.
I haven't used these yet, but right out of the package, I know that they run small. These are not for girls/women with a lot of hair. And I'll just say it: Or if you have a big head. Basically, there's a small, thin "plastic like" cap (kinda' like a thinner version of what you know a generic shower cap to be) with an elastic band sewn to a "satiny" cap. I wasn't expecting "satiny". I have yet to use them, but just know that they run small. I only purchased them so that I could shower while heavily conditioning my very fine - and thinning - locks.
