I do, I can’t really sleep without one anymore anyway (I have locs) so a bonnet keeps the lint out of my hair I also wear it all day if I’m not going outside—it’s a great investment.
If you buy one I would recommend getting a bonnet with long straps that you can wrap + tie around your head I find that the caps become loose after a couple of washes or when your hair grows it doesn’t really do the job like a bonnet with straps.
