Nai’vasha’s number one tip for keeping your curls healthy involves silk (or satin) protection. “Every day, anyone with curly hair should silk-protect to retain moisture,” she says. “It could be a bonnet, scarf, or pillowcase.” What most don’t realize is that sleeping on harsher fabrics like cotton can do more harm than good for your curls. When your strands rub up against cotton, it can cause friction, static, frizz, and make them dry. This is a no no for curls especially because curls are already naturally on the drier side. Wearing a silk or satin bonnet at night can help keep curls from getting frizzy and dry.
I personally sleep with an adjustable Yanibest satin bonnet on at night that I got on Amazon. It really does help my hair retain moisture. I apply a hair oil before throwing on the bonnet and wake up with softer, more manageable hair.
