What is a common material used for bonding hair extensions?

Keratin is widely recognized as a common material used for bonding hair extensions due to its ability to create a strong, durable connection that mimics the natural structure of hair. Keratin is a protein that naturally exists in human hair, making it highly compatible for extensions. This compatibility allows for a more seamless blend with the natural hair and enhances the longevity of the extension application.

Additionally, the bonding process often involves keratin that is melted and attached to the natural hair strands, which not only provides a secure hold but also ensures that the extensions move naturally with the hair. This method reduces the risk of breakage and damage to the natural hair, making keratin a preferred choice in many professional settings for hair extension applications.

Other bonding materials, while sometimes used, do not offer the same level of integration and natural look that keratin provides, highlighting its significance in the hair extension industry.
