It automatically pulls the hair through the micro ring. And then, just squeeze the ring . It is done.You may adjust the length as your hair grows : simply using the plier to open the micro ring and push the extension back up towards your scalp . and then re-clamping the micro ring shut. If you want to remove the extension, all you have to do is to open micro ring and remove it.
