I had been using the same two old bonnets for years that were not even satin lined. They would always fall off my head while I sleep. I decided I needed an upgrade because my hair is longer and more dense. This was the best thing I got for my hair recently! If I have twists, I can adjust it for it to fit my head while I sleep. If I have it in a pineapple, it also fits snug so it will preserve the style. Truly amazing product for natural hair.
