Our 13x4 frontal wigs are made with a HD lace frontal that measures 13 inches wide (from ear to ear) and 4 inches deep (back from the hairline). 13x6, 5x5, & full Lace wigs are also available .The hair strands on the frontal are hand-tied to a HD sheer lace base, which provides the illusion of a natural hairline and scalp. The rest of the wig's cap is typically constructed from a more durable, machine-made material which is mad with 2/3 depending on the density.
