Which technique allows for seamless blending of the extension with natural hair?

The technique that allows for seamless blending of the extension with natural hair is tape-in extensions. This method involves applying adhesive strips of extensions directly to sections of the natural hair, which creates a flat and cohesive look. Because the extensions lay flat against the scalp, they are less visible and blend more naturally with the wearer's hair.

The adhesive used in tape-in extensions is designed to be durable yet gentle, allowing for a comfortable wear that can last several weeks with proper care. Additionally, tape-in extensions are typically made with high-quality human hair, which can be styled and cared for just like natural hair, further enhancing the seamless appearance.

In contrast, other options like braids, clip-in extensions, and wigs do not offer the same level of blending and natural appearance. Braids can create noticeable bulk, clip-in extensions can leave clips visible or create uneven shapes, and wigs may not always fit snugly or match the natural hairline, making them stand out more than desired. Therefore, tape-in extensions provide the best solution for achieving a straightforward and blended look with natural hair.
