What technique, known as "Balayage," is characterized by freehand highlighting?

Balayage is a highlighting technique that is distinguished by its freehand application method. Unlike traditional highlighting methods that often involve the use of foils or specific tools for precise sectioning, balayage allows for a more natural and sun-kissed appearance. The stylist uses their brush to paint the lightener directly onto the hair, creating soft, graduated effects. This technique is particularly favored for its ability to add dimension and create a soft, lived-in look, without the harsh lines that can sometimes result from other methods.

The focus on freehand application in balayage enables stylists to customize the highlights according to the client's hair type and desired outcome, making each application unique. This method contrasts with those that use foils or tools, which can restrict the stylist's ability to blend and create that effortless appearance. Therefore, the correct answer accurately highlights the defining characteristic of balayage as a freehand technique.
