The Butterfly weft was created for braidless installs using micro links. These installs are great for maximum versatility. Our Butterfly weft is created for easy installation while adding plenty of density. One bundle typically allows for 3 rows of installation. A full install usually requires at least two bundles. If your natural hair is more dense than normal or you desire more fullness 3 bundles is recommended. Please use your discretion or refer to your stylist.
