Lather and massage shampoo through wet hair from root to ends. Leave on for 2-3 minutes, then rinse thoroughly.
Keep track of your tone: if you're loving your tone, keep up your routine as is. if you notice brassiness peeking in, increase use of Bust Your Brass an additional time per week. If you are a little too cool-toned and nearing a violet tone, cut back on the Bust Your Brass routine for a week or two.
Pre-caution: Avoid contact with eyes.
