1. A technique to darken hair

2. A technique to create highlights using aluminum foil

3. A permanent wave technique

4. A hair color application method

The correct answer is: A technique to create highlights using aluminum foil

Foil highlighting is a specific hair coloring technique that involves the application of lighter hair dye or bleach to strands of hair, which are then wrapped in aluminum foil. This method allows for precise placement of color and is designed to create distinct highlights that stand out against the base color of the hair. The use of foil helps to isolate the strands being treated, allowing for better control over the application and ensuring that the highlights process evenly without overlapping with the other sections of hair. This technique is popular for achieving a natural-looking sun-kissed effect, as it allows the stylist to add dimension and brightness to the hair without altering the overall color too drastically. The foil acts as a barrier, reflecting heat back to the hair and accelerating the lightening process, which can enhance the effectiveness of the dye used. In contrast, other methods mentioned, like darkening hair or applying a permanent wave, do not involve the specific procedure of isolating hair strands with foil, thereby clearly distinguishing foil highlighting as a unique hair coloring technique.
