Covering your hair with aluminium foil before bed: Why people try this unusual hair-care hack and what it is supposed to do
A unique overnight hair hack suggests wrapping damp hair in aluminum foil for enhanced body, waves, or curls, without the use of heat. By trapping moisture, the foil slows drying, enabling better shape retention as you sleep. For frizzy areas, a separate dry foil technique can provide instant smoothness. Keep in mind that results may vary according to your hair's texture and its ability to retain styles.
