What is a blending technique used to make hair extensions look natural?

Layering or texturizing the extensions is a technique that helps in creating a more natural appearance when integrating hair extensions with natural hair. By incorporating layers or varied textures, the extensions can blend seamlessly with the client's existing hair, reducing the likelihood of a stark contrast that might otherwise reveal the presence of the extensions. This method allows for movement and dimension that mimics the way natural hair behaves, making it less noticeable.

Twisting the ends of the extensions may provide some styling benefits but does not significantly contribute to blending for a natural look. Using lighter colors at the ends can create a highlight effect, which may or may not suit the individual's hair type or desired style. Applying heavy oils to the scalp lacks relevance to blending techniques for extensions, as it focuses on scalp care rather than the visual integration of hair extensions.
