New Upgrade: The heatless curling iron inside has been upgraded with premium coral fleece material, a curling headband that is more non-slip and soft, flexible and elastic compared with the old stiff artificial silk and foam. The new upgraded heatless hair curler is more suitable for sleeping. Fantastic Results: These heatless waves can be used without electric heat products because heat potions or products on our hair cause a lot of damage to our hair and seriously weaken our hair and it can fall out. The heatless curls are designed to fit closer to the head, making them less likely to slip and cause discomfort. Simply wrap your hair around the hair band and you will get bouncy curls. Convenient and Time-Saving: Place the curling band on your sleeping head and secure it with a hair clip (slightly damp hair). Wrap your hair around it strand by strand, tie the ends of your hair with silk elastics, repeat on the other side. Wait 3-6 hours or sleep overnight, curl your hair without heat and you'll get your gorgeous curls! Styling spray ensures longer lasting curls.
