The small micro rings hair extensions are made from copper with a silicone lining to grip and protect your own hair. There is no glue, heat, sewing or braids involved. Micro Ring hair extensions can stay in for up to six to nine months, as you can have them moved up and re-tightened every eight weeks.
This method is best suited to medium and thick hair, and darker hair colours. If they are applied to very fine hair, they may slip down or be visible, and they may also be visible in lighter shades of blonde hair. The micro rings extensions are available in a variety of different colours to match your hair colour. The rings are clamped securely in place, and those who wear micro ring extensions say that they are comfortable day-to-day and feel completely natural.
