THIS PAGE: To enhance hair with a deep shade, Jackson mixed 1/2 5GD (Light Golden Brown) and 1/2 4N (Medium Brown), applying the formula to strands before cutting them into a classic bob shape with heavy fringe. For added impact, she texturized the ends. FACING PAGE: To produce an ash undertone in the hair with a watery copper effect over the top, Jackson called on her water-wash technique, which involves tinting the entire head with 11HA (Super Lightening Ash Blonde); adding a fine splash of highlights using Naturlite Lightening Powder, 6% ( 20 vol) Cream Activator and Naturlite Oil; and then toning with 8CA (Caramel) and 3% ( 10 vol) Liquid Activator.
