Freshen up existing color and add just-colored shine with a quick-n-easy salon technique — glazing. Pick a color one shade lighter than your current level 3 color. Some of the best shades for glazing are 02 Sahara Light Blonde, 04 Sunflower Medium Golden Blonde and 07 Coral Shell Light Reddish Blonde. Just pick up a box of Natural Instincts and follow these directions:

In a clean, empty shampoo or applicator bottle, mix:

1/2 bottle of the Natural Instincts colorant
Apply all-over damp hair according to the package directions. Leave on for 5 minutes. (10 minutes for more intense results)
Rinse and you're done.
For even more vibrant color results, just leave out the shampoo.
