I have fine, neck length 2c/3a curls that lose their volume easily in the desert climate where I live. Every other sleep cap I've tried (looking at you, slap) has flattened the living daylights out of my curls. This wrap is the only thing that preserves my volume overnight! I can now go 5-6 days between washes with only a light refresh in the mornings. It saves me so much time, and I love that it makes me look like a 1940s Hollywood starlet instead of a cancer patient! Will definitely be getting more in other colors.
