I have brittle, easily tangled, straight, flat Caucasian hair and have found that the nights I sleep with the silk cap help my hair be less tangled and more smooth in the mornings. The cap has a tie to hold it on: I had to tie a knot so it wouldn’t untie and just float away in my bed at night. I don’t notice that it is on otherwise as it is pretty comfortable. Shipping was super slow, but it did eventually arrive.
