A lace front, or lacefront, is made from a woven polyester material like extra-invisible nylon stockings that is very hard to see when it is placed against the skin.

The hair is knotted into the lace and appears to grow from the scalp. Normally the knots are bleached so that darker hair does not appear dotty.

The front edge of a hairpiece is the most important area. It is the part that is always detected if you wear a bad hairpiece. Only some variations of a lace front and some polyskins can be trusted to maintain the illusion of growing hair at an exposed front edge.
