Lace frontals and lace closures are both very useful in creating beautiful sew-in installations. They serve the same purpose, which is to close off an install and eliminate the need for blending. The lace is made of either Swiss lace or French lace. Closures are typically 4×4 inches while frontals are 13×4 inches. Lace frontals are bigger mainly because they run from ear to ear to cover the entire hairline. Closures are installed in the front area of the head to close off the style.
