Our 100% Virgin Russian single 613 Human Hair bundle is the highest quality human hair on the market. Each selection has been collected from one donor. All cuticles are intact and you will notice each selection of our virgin hair has a natural taper at the end. This hair is much thicker and denser than Indian and Malaysian Hair and is an excellent blend for thick lustrous African American relaxed hair. All of our Virgin 613 Human Hair has undergone a stringent quality assurance process to ensure it is free of imperfections. Our Virgin Russian 613 human hair will last well up to a year with proper care and maintenance.
