The Nano Ring is the smallest and most innovative way to apply hair extensions currently on the market. These extensions are very comfortable, and the rings are so tiny, they are almost impossible to detect, even when you are wearing your hair up in a ponytail.
The nano ring can only be used to attach nano-tip extensions to your hair; the regular I-tip hair extensions are too big and will not thread through the nano ring. At the end of each hair extension is a tiny wire. This is different than the tip of an I-tip hair extension, which uses a keratin bonding agent to glue the hair together; because of the wire, nano-tip extensions both are lighter and allow your hair more freedom of movement. You attach the extension by threading both the tiny wire and the hair it will be attached to through the nano ring then clamping the two together using pliers to crimp the nano ring.
The hair I have purchased lasts up to three years with good care, and the actual application can last up to six months. Because of this, nano rings make for a very low-maintenance hair extension. It is also very easy to fix extensions that have slipped or grown out.
When purchasing hair, make sure you choose Remy 100% human hair. The extensions will be in your hair for a long time, and while you will want to save money by doing the work yourself, I recommend you don’t. Application can be very time consuming and tricky (such as loss of hair) if not done correctly.
Just offering a little of my experience and knowledge.
