Nano Tip Hair is a type of hair extension that is attached to the natural hair using a tiny bead or ring. The extension itself consists of small strands of hair, typically about 1mm wide, with a small metal tip at the end. The metal tip is coated with a layer of keratin, a natural protein found in hair, to make it stick to the natural hair. The nano tip extensions are lightweight and can be used to add length, volume, or both to the natural hair. They are also known for being discreet and comfortable to wear, making them a popular choice among those looking for a natural-looking and long-lasting hair extension solution.
