Single Layer Weft Extensions are hair extensions that can be attached in several different ways. The weft attachment is very thin and flexible for maximum comfort and a result without visible edges. The hair is real Remy human hair with intact cuticles all facing the same direction, which gives a natural flow, beautiful shine, and a silky feel that lasts over time. Single Layer is perfect for discreetly adding length, volume, and color effects to your natural hair.
