The method of attaching extensions to a client's own hair using a bonding material and heat from a special tool is known as fusion bonding. This technique involves using keratin-based adhesive that, when heated by a specialized tool, forms a bond with the natural hair. The heat causes the bonding material to become pliable, allowing it to adhere securely to the hair strands. Once cooled, the bond hardens, providing a long-lasting attachment that can withstand daily activities.

Fusion bonding is popular due to its ability to create a seamless look. It provides flexibility in styling and can be used on various hair types, making it a versatile choice for many clients seeking to enhance their hair with extensions. Careful application and removal are essential for maintaining the health of the natural hair and the extensions, which is why this method requires proper training and technique.
