We use the best materials on the market to make perfectly groomed, unstoppably good hair systems. However, we do not guarantee the lifespan of any hair system. Any mention of the lifespan of our hair systems is an approximate. Wear and tear of any hair system is solely dependent upon the wearer's care and maintenance. We recommend that gents have at least two hair systems on hand to rotate use and have as a spare in case a unit needs repairs.
