Mine does. The looser my hair is the more tangled it gets. That’s not to say I have to sleep with a protective style that’s just super tight, but my hair does need to be separated when I sleep.
A satin scarf does help, but depending on how hard you sleep on your pillow, sometimes it doesn’t do much to prevent tangles. So long as the majority of my hair is protected and put up in some way, the tangles aren’t that bad.
I usually either braid or twist up my hair, spray my hair down with water really good, put on my bonnet, and then either a hat or my beanie. Usually my bonnet stays on better that way
