I have been using my fold for a year now and I can say with full confidence I'm never going back. I sleep with it on every night and not only has my hair become denser, stronger and longer but my hair line has visibly improved. It's breathable, adjustable, stays on all night without any pinching, pulling, or headaches in the morning. And it's easy to wash on top of it all! Yes, it's expensive for a sleep bonnet, but I would spend that money all over again. I cannot sleep without my Paradise Folds.
