The method referred to as "overlapping" is not recognized as a standard technique for applying hair extensions, making it the correct answer to the question. In the context of hair extensions, each of the other methods—fusion, clip-in, and tape-in—are established methods used by professionals in the beauty industry.

Fusion involves bonding extensions to the natural hair using a keratin-based adhesive that requires heat, creating a seamless integration. Clip-in extensions are temporary and can be easily attached and removed using clips, allowing for flexibility in styling. Tape-in extensions involve adhering a weft of hair using a special tape that sandwiches sections of natural hair, providing a semi-permanent solution.

In contrast, "overlapping" does not clearly refer to a recognized method for applying hair extensions and could lead to confusion. Understanding these distinctions helps clarify the various techniques available in hair extension application.
