Closure and frontal pieces are the last pieces needed to accompany the installation of your human hair extensions. Closures and frontals are placed on or around your crown area, to blend right in with your hair extensions. These hair pieces are easy to maintain and style and can be parted in any direction. These pieces will give you the crown confidence you've been looking for. The bases are made of Swiss Lace or Silk Base material meant to mimic the scalp, giving you a snug and realistic fit.
