Satin bonnet
A type of headwear made from satin fabric, designed to protect hair while sleeping. It helps to keep hair frizz-free and tangle-free by reducing friction between the hair and the pillow, and often comes with adjustable features to ensure a secure fit throughout the night. Satin bonnets are particularly popular among individuals with natural, curly, or textured hair, as they help to maintain moisture and prevent breakage.
