Lace wigs are so called because, as Marylin Paul of High Definition Hair states, "Whenever a lace wig parts, you just see netting or lace that in some cases is dyed to match the color of the hair. Whereas whenever a High Definition Wig parts, whether you part it or it parts on its own, people actually think they are seeing your scalp, when in fact they are seeing the base of the wig." The makers of lace wigs are not eager to share their trade secrets on how these wigs are actually made. Suffice it to say, lace wigs are prized because of the fact that they look so natural and are made from human hair or are made so well they look like they're made of human hair. There are different kinds lace wigs that work well for different kinds of hair loss.
