Micro Loop hair extensions are a great way to easily add volume to your hair. There is a string at the top of the loop and a micro ring already attached. All you have to do is put your hair through the loop and pull the string. It automatically pulls the hair through the micro ring and all you have to do is squeeze the ring.
These are also a great way to add streaks to your hair if you choose a different colour than your natural hair colour.
Micro Ring extensions have also become very popular as they should not damage your hair.
