What is it called when you combine two different highlighting techniques?

The correct terminology for combining two different highlighting techniques is "Hybrid Highlighting." This term describes the practice of using more than one method to achieve specific and customized results in hair color. For instance, a colorist might combine traditional foil highlights with balayage techniques to create a multidimensional effect that enhances the hair's texture and depth while maintaining a natural look.

Hybrid Highlighting allows stylists to tailor their approach based on the client’s preferences and hair type, providing flexibility and creativity. It's particularly popular because it offers the benefits of both techniques—precision from foiling and softness from balayage—resulting in a look that is stylish and unique.

The other choices refer to different concepts or do not specifically address the combination of techniques as intended in this context. Therefore, Hybrid Highlighting is the most accurate term to describe this creative approach in hair coloring.
