    How does hair just take shape without the addition of heat or rewetting hair? Sometimes you wake up and the hair, despite combing, retains a permanent “reconfiguration”.

    @DaveStone That’s due to mechanical stress  but that’s something you don’t want to intentionally put your hair under.

    It’s also due to hydrogen bonding. When you sleep, you sweat. Water gets on strands and can cause bonding within the fiber and between fibers.

    I’ve begun using a bonnet to protect my hair. I think it’s working but I wake up with wavy hair.
