This is made possible thanks to our unique state-of-the-art polymer, consisting of a compound made of a molecular structure very similar to that of human hair, which provides a transparent and virtually undetectable bond allowing it to contract and expand much like human hair without the damage. The HairXtend System Consists of a strand-by-strand application method, which unlike most other systems does not implement the use of fancy machines, but rather a simple and very effective manual application.
