Bead hair extensions are a type of hair extension method that uses small beads or micro rings to attach the extension hair to the natural hair. The process involves threading the natural hair through a small bead or micro ring, then sliding the extension hair through the same bead or micro ring before clamping it shut with pliers.

Bead hair extensions are a popular method of hair extension because they are easy to install and remove, and do not require the use of heat or adhesives. However, they may not be suitable for everyone, as they can put tension on the natural hair and may cause damage if not installed and maintained properly.
