If nighttime is your only time to wash your hair:

• Use a microfiber towel to soak up extra water.
• Dry it about 80% before sleeping.
• Sleep on a silk pillowcase to cut down on friction.
• Keep your hair loose or in a gentle braid — skip the tight ponytails.

Final takeaway

No, sleeping with wet hair won’t cause lice — but it can damage your hair and scalp if it becomes a habit. Knowing the facts lets you care for your hair more mindfully. Your scalp (and your future self) will thank you.
