amika Bust Your Brass Cool Blonde Shampoo

Same formula you love, fresh new look!

Buttery blonde hair with zero brassiness? It’s totally possible. The violet pigment in this shampoo cancels out those harsh yellow tones that usually appear in pale, cool colors. The formula is pH-balanced and sulfate-free, meaning it won’t strip your hue or fade it fast. It also contains deeply nourishing ingredients like avocado oil, wild cherry bark extract, and sea buckthorn seed oil, so you don't have to compromise hydration for color protection.

Lathers nicely, brings out the blonde highlights and makes my hair feel smooth but not weighed. I use the conditioner also. Both smell great, which is a plus.

Best violet shampoo

I have been a fake blonde for 18 years! That being said I’ve tried literally every violet shampoo under the sun! This is the only one I’ve found that not only delivers incredible strength through its toning power but also a deep clean that moisturizes and also smells AMAZING! Most violet shampoos smell awful and leave my hair feeling dry and damaged- not this shampoo at all! I will never use another violet shampoo after finding this!

Will not use again
Sampled

I am use to using darker purple to tone my hair so this did absolutely nothing in that department. The product is the faintest shade of lavender. Would be good for blondes who are scared to use purple on their hair. Other than that, I didn't notice anything special about the product.

Summer Blondes Need This

Great for my summer pixie. Kept the brassy at bay. Great smell and didn't leave stands limp. It did everything it was suppose to do.

Really cool color!
Sampled

I tint my hair with color and shampoos, as I am a total highlift blonde. This shampoo made the most lovely color of violet in my hair. It washed out within a couple of shampoos, and I have bought this product in the stores.

Great
Sampled

This shampoo is great. My hair felt so soft and light. My hair is a little too dark for this type of shampoo though. I’m more a dark blonde. I think this product would be perfect for someone with color treated light blonde hair! But still i liked this shampoo because like most other amika products it gave my hair bounce and shine and super softness. Light blondes grab a bottle now!

I am a blonde and this shampoo made my hair shine and feel good when dry. I may possibly purchase this product from Birchbox.

Love it!!!!!
Sampled

So I had been fighting my hair...in a short, layered cut. This shampoo and conditioner has not only tamed my hair and made it more manageable but the color looks so much better. Hard to believe a shampoo can do that. I was able to get three washes from the sample (thank you Birchbox) and it has just kept getting better. I'm a believer!

I’m obsessed. One of the purple shampoos I enjoy using. Smells great, does the job, leaves my hair feeling clean. I noticed a difference while using this.

Seriously works
Sampled

Can tell the difference after use. I use it on days when I want my hair to look better than usual. Not sure if it works permanently if used daily, but certainly provides a nicer color the day it’s used.
