After shampooing, gently massage Bust Your Brass Mask through wet hair from roots to ends. Leave it on for 3-5 minutes, then rinse. Use it as a weekly intensive treatment in place of conditioner.
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.

Game changer
This is a purple masque that is not actually purple, it's a blue-violet which is PERFECT for brunettes or brunettes with a balayage.

great product, a little purple
I love the mask and how my hair feels. I have been blessed with prematurely white, not gray, hair so the pigment really picks up. I really didn't want to be one of those lavender haired older ladies but alas, it happened after the first use.

Thanks to my hairdresser for introducing me to this hair mask. Wow the big change it made on my recently treated hair! Shipping took so long that I was trying to shop around locally, but I couldn't find at a better price than what I had ordered it. While waiting, I tried some drugstore brands and they worked well enough, but once I got and tried Amika's I saw the difference. I totally recommend it.
