Selecting the right hair extensions may get pretty confusing due to a lack of accord among manufacturers of hair extension on quality levels. When selecting hair extensions, it is important to understand remy vs. non-remy and how they affect purchase decisions of hair extensions. Remy hair, basically, is aligned in a single direction. This means that the cuticle, which is the protective outer layer of each strand of human hair, is not inverted. If the cuticles of the hair are not pointing in a single direction, they may work contrary to each other resulting in hair extensions which are easily prone to snagging and tangling. Hence, remy hair does not in any way allude to the condition or quality of the hair; it only points out its longevity. Next is the “virginity” of the hair. Virgin hair extensions imply that the hair has not been subjected to any chemical treatment or coloring process and is being supplied in its original state. Similarly, hair can be either single drawn or double drawn. Single drawn hair has non-uniform strand lengths, since the hair is being supplied in its original state for a more natural look. Double drawn hair has uniform hair length, where either strands of the same length have been collated, or the original strands have been trimmed to a uniform size.
