The HM Julianne by Sepia is a 100% Human Hair Wig featuring a monofilament top. All of Sepia’s Human Hair consists of only the highest grade human hair. Monofilament refers to hair strands that are attached by hand-knotting them one strand at a time. This allows the strands to move more freely and provides a natural looking part. The monofilament material is more breathable due to this weaving technique.
