Micro Loop / Ring Hair Extensions
Micro rings or micro loop hair extensions use small metal rings (usually aluminium) lined with silicone with the extension hair attached. They are fixed to small sections of natural hair and tightened using a special tool that clamps the loop around the natural hair.
The micro loops are designed to be small enough so that they are not visible in normal use. They need repositioning every 2–3 months as the natural hair grows and the micro rings move away from the scalp.
