Wearing a bonnet can reduce your bedhead, stop your hair from drying out, and prevent dandruff from falling onto the bed. It also allows your expensive hairstyles to glide over the pillow and retain their shape. Bonnets are also useful in other aspects of life, including; Cooking, Hair-dyeing, Cleaning, Sleeping, and Daily Life. With good elasticity, common size fits for most women and girls, not easy to fall down.
