I love these shower caps! They are large enough to fit all of my long, thick hair underneath and still be comfortable enough not to pinch my skin or pull my hair. (Too many shower caps are so small that it seems like they would only fit a five-year-old or a little old lady!) Also, the plastic is strong enough so that it forms a good barrier so that my hair doesn't get frizzy even when I take a long, hot shower. (And to make extra-sure that no water escapes onto my hair, I have found that putting a layer of cling wrap along my hairline helps a lot.) In addition, these caps last relatively long. I would definitely recommend these to a friend. I just wish that they were sold at more stores.
