Straight Weft Extensions are straight hair extensions that can be attached in several different ways. The hair is real Remy human hair with intact cuticles all facing the same direction, providing a natural flow, beautiful shine, and a silky feel that lasts over time. Straight Weft Extensions can be used as a long-lasting hair extension with the beaded weft method and weaving, or as a temporary hair extension by creating your own custom clip-ins. Choose Double Layer for a weft that provides a full hair extension with lots of volume. Choose a Single Layer weft for a discreet hair extension or thickening.
