difference between balayage and foil
Difference Between Foils and Balayage The main difference between the two techniques is that the head is round and the foils are square. A square foil commits you to work within that square, whereas balayage allows you to move around freely carefully looking at the colors around the strand and working within the existing colors. So rather than taking a section of hair in a square foil (keeping in mind that the head is round) we carefully take pieces of hair from the head.
