What kind of hair extension method uses adhesives?

Bonded extensions utilize adhesives to attach the extensions to the natural hair. This method typically involves using a keratin-based adhesive that is melted and applied to the base of the extension and the natural hair, creating a secure bond that can last for several weeks to months, depending on the maintenance and hair growth.

The key characteristic of bonded extensions is their reliance on adhesives for attachment, making them a popular choice for clients seeking a semi-permanent solution. This method allows for a natural look and feel, as the extensions blend seamlessly with the client's hair.

In contrast, the other methods listed do not use adhesives as their primary attachment mechanism. Clip-in extensions are temporary and utilize clips for easy application and removal. Weft extensions involve sewing wefts of hair onto rows of braided natural hair, eliminating the need for adhesives. Micro-link extensions use small beads or links to attach the extensions to natural hair strands, allowing for adjustability and a more natural movement without the use of adhesives.
