Lace is a material known as "tulle" in the textile industry, which hair replacement companies use as the foundation for lace hair systems. It is a very lightweight, delicate material that appears transparent against the skin.

"Lace Front" hairpieces are becoming increasingly common, and some hair replacement companies make hair systems entirely of lace.

Not all lace is of equal quality. Many hair replacement companies use lace that rips and frays very easily. However, Joseph Paris Naturally has lace hair systems that last as long as two years.
