Flat tip hair extensions, also known as pre-bonded hair extensions, are a hybrid between I-tip and tape-in hair extensions. They lay flat and smooth, just like tape-in extensions, and can be installed using micro beads and rings (like I-tip extensions) or glue. Micro beads are used to clamp each strand in place. These beads fasten the extensions to your natural strands and will not make them slip off your head. Alternatively, they can also be glued to the hair using high-quality Italian keratin glue. These installation methods for flat tip extensions require absolutely no chemicals or heat.
