I wear a satin scarf. But if I am in braids (individuals) I wear a shower cap or night cap over them. I dislike the braids moving around touching my face and body at night. Creeps me out.
I use a bonnet and sometimes a satin scarf but I always sleep on a satain pillow case just in case my bonnet slips off. Also I notice that when my bonnet starts to slip off in the middle of the night its time to buy a new one.
I do some combination of the above (please tell which)
I always sleep on a satin pillow, so sometimes I wear silk or satin to bed on top of the pillow bc I am a wild sleeper and wanna keep it neat.
I sleep with a net that I cover my hair with then tie above to secure. I love it because if somewhere happens to be itching or pulling I can gently and quickly fix the situation without having to take the whole net off like I would have to do with a scarf. It rarely ever comes off too unless my hair is super smooth and silky on that particular night.
