Which technique is used to apply hair extensions?

The technique used to apply hair extensions includes bonding, weaving, and clip-ins, which are all methods specifically designed for securely attaching hair extensions to either natural hair or sections of hair.

Bonding involves the use of adhesive to attach the extensions, creating a seamless look. Weaving technique entails braiding natural hair and sewing the extensions in, ensuring they blend well with the client's hair. Clip-ins are temporary extensions that can be easily attached and removed, allowing for flexibility in styling without a commitment to a long-term method.

Other options provided do not accurately represent techniques for applying hair extensions. Fusing or braiding refers to methods of combining or intertwining hair and does not cover the full range of extension applications. Curling or straightening are styling techniques rather than application methods, while shampooing or conditioning is part of the hair care process, unrelated to the application of extensions.
