Protecting your hair at night
After setting your hair for the night, use a silk or satin bonnet or scarf to prevent the hair from losing moisture and from snagging on traditional cotton pillowcases. Many like to use both when wrapping the scarf around the sides while protecting the exposed hair at the top with a bonnet.
If you don't like the feeling of anything on your head while you sleep or think you just don't want to be bothered with any of the above, a satin pillowcase may be the answer for you! You can toss and turn all you like without worrying about a bonnet slipping off while still maintaining the moisture.
