During the night, you have options with your hair. You may decide to braid or twist it with hair butter to prevent breakages from the pillow and retain texture. A couple of twists or braids will do. You can also get a scarf to wrap the hair or a satin pillowcase to sleep on. The two will help eliminate the rubbing since the cotton will suck the moisture from your hair. A third option is the use of pineapple on your hair. It will help in preventing loss of the curls and tangling during the night.
