This coloring technique is designed to soften heavyweight areas, particularly for thick hair. A block foiling technique is used, with alternating colors and directions. You learn to begin by creating 4 even cube sections, paneling down the middle of the head to the nape. Each section is then sliced with foils, alternating the direction of slices from vertical to horizontal. Colors are selected in consultation with your client, which are then alternated in each slice. The color is applied from the roots to the ends of the hair. These lightening techniques within the interior of the hair style provide a dramatic finish, which can be personalized for each client.
