What are micro-links used for in hair extensions?

Micro-links are tiny beads or fasteners that are primarily used to attach hair extensions without the need for heat, glue, or other chemical adhesives. This method involves threading small sections of natural hair through the micro-link and then adding the hair extension to that section before tightening the bead to secure everything in place. This technique is favored for its ability to create a more natural appearance and reduce damage to the natural hair compared to methods that rely on adhesives or heat.

The other options involve techniques that do not align with the primary function of micro-links. Creating curls without heat pertains to styling techniques, while adding color relates to hair dyeing or highlighting methods. Securing wigs deals with attaching wigs to the scalp, which is a different application altogether.
