Micro Rings Method
This method makes use of a weft of hair as compared to strands. Here each extension is attached to a strand of your hair with a tiny ring. This method continues until all the strands in the weft are attached to the natural hair. This is a great method to opt for if you have thick hair or plan to dye your hair or use heat-styling methods. They last for about 3-4 months.
