Remy hair extensions are made from virgin human hair of the highest quality grade. Remy hair extensions are the most popular human hair extension on the market. There may be some chemical treatments involved after the raw material is acquired (hair dye or cuticle removal). The hair collected is healthy, the cuticles are intact and all cuticles flow in the same direction from root to the tip. There will be almost no tangling and matting if processed properly, for all hair strands follow the same direction.
