Balayage and highlights are both hair coloring techniques used to add dimension and depth to the hair, but they differ in how the color is applied and the resulting look.

Balayage is a French word meaning "to sweep" or "to paint." In the balayage technique, the color is painted onto the hair in a sweeping motion, creating a graduated, natural-looking effect. The color is usually applied to the mid-lengths and ends of the hair, with little or no color applied to the roots. This allows for a more subtle and gradual transition from the natural hair color to the dyed color.

Highlights, on the other hand, involve sectioning off small chunks of hair and applying color to them. The color is usually applied to the entire length of the sectioned hair, from roots to ends. This creates a more noticeable contrast between the natural hair color and the dyed color. Highlights are often placed around the face to frame it and add brightness to the hair.

One of the main differences between balayage and highlights is the final look. Balayage tends to create a softer, more natural look, while highlights can give a more dramatic, bold effect. Balayage is also lower maintenance than highlights, as the color grows out more seamlessly and does not require touch-ups as frequently.

Both balayage and highlights can be done using a variety of coloring techniques, such as foil highlighting, cap highlighting, and hair painting. The best technique for you will depend on your desired look and the condition of your hair. It is always recommended to consult with a professional hair stylist before deciding on a coloring technique.
