Balayage is a fancy French word that means "to sweep." It is a special way of coloring your hair that gives you a very natural and sun-kissed look.
So, imagine you are playing with paint brushes and colors, but instead of using lots of paint on your hair, your hairdresser will gently brush a little bit of color onto your hair in different places. It's like they are using a small broom to gently sweep the color onto your hair.
This way, you end up with some parts of your hair lighter and some parts darker, just like how the sun would naturally lighten your hair if you spent time outside.
Balayage is a popular hair coloring technique because it looks very natural and low-maintenance. Who doesn't love feeling like they just spent all summer at the beach?
