Micro-bead hair extensions are a type of hair extension that is looped through the natural hair and then clamped with metal beads by using pliers. They are a popular alternative to clip-in hair extensions.
The micro beads are lined with non-slip silicone, which allows them to retain a secure grip. They don't cause damage to hair or scalp, because the application process doesn't entail the use of heat and glue. If a person keeps the beads in good condition, they can last up to six months. One of the advantages of micro-beads is that they can be easily be moved up once they slip down the hair shaft.
