is a relatively new extension method. This method has been developed in a quest to find the most undetectable methods of installation. The essential difference is that nano rings are 90% smaller than regular application rings. The hair has a strong keratin tip which secures a fine metal loop which is squeezed closed to form a strong tip that is inserted into the ring before being clamped with pliers. Nano-Tip extensions are lighter and allow your hair more freedom of movement.
