These clip-in hair extensions are made from 100% remy human hair that blends naturally with your own. The 16-inch length in chocolate brown to honey blonde ( 4/27) adds subtle length and volume. Each set includes 8 pieces with 18 clips using double weft construction. Apply them in about 5 minutes without glue or tape - the strong clips stay secure without damaging your scalp. Style them with heat tools, dye them, or curl them just like natural hair.
