Wefts are bundles of hair sewn into tracks, typically weighing between 3.5 to 4 ounces per bundle. These wefts are a popular option for those who want to install their hair with a sew-in or for wig-making. They come in a variety of textures and lengths, including straight, wavy, curly, and kinky. Wefts provide a customizable approach to adding volume, length, or thickness to natural hair, and they are especially ideal for those looking to create a full, voluminous look. Wefts are easy to install and can last for several months with proper care.
