Brazilian hair extensions are made from human hair harvested from donors of Latin American or Brazilian origin. Given this fact, selecting correct Brazilian hair extensions may still get pretty baffling due to a lack of consensus among manufacturers of Brazilian hair extensions on color shades, thickness, quality, etc. When selecting Brazilian hair extensions, it is important to understand Remy and non-Remy hair, and how it affects purchase decisions of the Brazilian hair extensions. Remy hair has its cuticles intact and aligned in a single direction. The cuticle is the protective outer layer of each strand of human hair. If the cuticles do not point in the same direction, they can work against each other due to which the Brazilian hair extensions are then prone to catching up with one another and getting tangled. Remy hair does not refer to the condition of the hair, but only its longevity. Next is the “virginity” of the Brazilian hair extensions. Virgin Brazilian hair extensions are made from hair which has not been chemically treated or colored and supplied in the original form. After chemical processing or coloring, the hair is referred as non-Virgin. Further, Brazilian hair extensions can be either single drawn or double drawn. Single drawn hair is supplied in its original state for a more natural look and hence has strands of differing lengths. Double drawn hair has uniform hair length, where strands of similar lengths are collected and trimmed to a uniform size.
