Usually, Remy hair is Indian in origin. Remy hair refers to human hair that has been harvested from the scalp in such a manner as to keep the cuticle pointed in the same direction as the hairs next to it. Remy hair is simply shorn from the head and bagged up with no regard for the way the cuticle layers of the hair shafts are aligned. This haphazardly harvested hair must be chemically processed to remove the cuticle layer from the hair shaft, since hair whose cuticle layers are running in opposite directions tends to become tangled and knotted together. Remy hair is gathered from the head of donors/producers in such a way as to keep the hair properly aligned in relation to its neighboring hairs.
