Sleeping With Weaves
If you have either natural wave or straight weaves, be sure to tie these down and use either a silk or satin cap to cover your hair before going to bed at night.
Never wrap your hair in any kind of cotton material, as this will only absorb oils from your hair that can make it much less manageable. You also should not use any elastic bands since these can cause various amounts of stress. Always brush your hair prior to going to sleep, and you can even braid your hair as well.
