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.

Bust Your Brass Saved My Hair
Okay, my hair story is a long, painful process and I'm sure my hairdresser friends twitch slightly when I talk about it. I decided rose gold was going to be a good hair color choice for me.

My hairdresser recommended Amika for my gray hair to help with toning. Needless to say this shampoo does not disappoint. It smells and feels good in my hair. I receive so many complements about how beautiful my hair looks!

This is great for getting the yellow and brassy tones out of your hair. It is strong so you don't have to use it as often so it lasts longer.
Simply the best!

I've been platinum blonde my whole adult life, I've used many different high end and low end toning products but nothing ever compares to Amika's purple shampoo and conditioner duo. I ALWAYS come back to it! It's simply the best! Non drying, gentle yet very effective and banishes any brass or yellow tones, brightens dull blondes!
Amazing
