I'm new to the whole curly girl method and heard that sleeping with a satin night cap helps for some reason.
I went to my local Sally's and purchased the first one I saw. I came home only to realize that my new cap isn't completely satin! This is what I mean: http://www.cachebeauty.com/satin_touch-on_cap.jpg

Only the bottom half is real satin, and the label doesn't give me any info on what the other material is (though it feels like some sort of soft tulle)

Will this be a problem for my hair? Should I invest in a completely satin cap or will this get the job done?

*also: i was wondering why satin is recommended in night caps and pillow cases as opposed to other materials, is it supposed to be good for your hair? thanks!
