Highlights and balayage are two techniques that are used to add dimension and depth to hair.

Highlights involve applying lightener or hair color to specific sections of the hair, typically using foil to separate the sections. This technique is often used to create a more dramatic, bold look.
Balayage, on the other hand, is a more subtle and natural-looking coloring technique. It involves painting the lightener or hair color onto the hair, starting at the mid-lengths and working towards the ends. The result is a more seamless, graduated color effect.
Both highlights and balayage can be used to add dimension to the hair, but the end result and the application process are quite different.
Here are some additional details about highlights and balayage:

- Highlights are typically more noticeable than balayage, as the sections of hair that have been lightened are usually quite distinct. This can be a good thing if you want a bold, noticeable change to your hair, but it may not be as suitable if you want a more natural-looking result.
- The placement of highlights is also generally more precise than with balayage. With highlights, the stylist will typically place the lightened sections in a specific pattern, such as around the face or in a sun-kissed pattern. Balayage, on the other hand, is more freehand and organic, with the lightener or color being painted on in a more haphazard manner.
- The maintenance of highlights and balayage can also be different. Highlights typically require more frequent touch-ups, as the regrowth is more noticeable. Balayage, on the other hand, can be more low-maintenance as the regrowth is less noticeable and the color fade is more gradual.
Overall, the choice between highlights and balayage will depend on your personal preferences and the desired end result. A good stylist should be able to help you decide which technique is best for you based on your hair type, length, and desired look.
