This new type of hair extension is not yet known on the global market, but has become popular with many customers very quickly. For micro ring extensions customers, in future they can use nano ring extensions, because they are up to 90% smaller than microrings. As easy as you can use them, you can also remove them. Simply loosen the ring and peel off the strand. The reuse of these strands is not a problem either, you need new nanorings, which are very cheap to buy. If you specify the density of your hair as normal, usually 100-125 strands are sufficient for a complete hair extension.
