Balayage is a French hair coloring technique in which the color is painted onto the hair in such a way as to create a sun-kissed look. The word "balayage" means "to sweep" in French, and the technique involves using a brush to apply the color to the hair in a sweeping motion.
Balayage is a popular choice for medium-length hair, as it can create a natural-looking, dimensional color that complements the length of the hair. It is also a low-maintenance technique, and the color can last for several months without needing to be touched up.
