Black Brown Invisible Wire Hair Extension Wavy Curly Synthetic Hairpiece Long 20 Inch Specification： Each pack includes: 1 piece of 2 clips in wefts; 2 wires in different length for replacement; adjustable hooks get the most suitable size. Upgraded wire is thicker and more elastic, not easy to break and not cause any pressure on the scalp. Secure Fit: 1. 2 clips sewn on the weft will keep the hair extensions stay in place.                         2. Thicker and invisible wire allows the extension to lie smooth and flat on the head like a secret headband.                         3. New S Hook will prevent the wire from falling off. Ways of wearing： 1. Position the wire hair extensions on your head like a headband, secure them with 2 clips, and hide the wires with your own hair. Care Tips: Unlike your own hair, this hair extension may get tangled without nutrition. You can use detangle spray or get a spray bottle and put some conditioner in it and add water. If there is no conditioner, just spray some water, then use a wide tooth comb to brush it. Start from ends and work towards the root to decrease shedding.
