bust your brass cool blonde strength repair shampoo

I love this shampoo. I’m a natural blonde who gets highlights, and they do get brassy, as is natural. But this shampoo fixes that. It prevents any brassiness, keeps my blonde hair nice and bright, and delivers. It smells amazing. My hair gets super clean and I only wash it once a week. It’s high quality, thick shampoo so you don’t need much, it lasts a long time. The bottle doesn’t leak, as others have said, but I also don’t let shampoo residue build up around the opening that could prevent the cap from properly closing. I will keep buying this shampoo forever

I really like this shampoo. Allows my hair to be shiny, not dull, and not brassy. Cleans well today. Has a light pleasant scent.

I’ve tried countless purple shampoos over the years, but this one is hands-down my favorite—and I’ll definitely be repurchasing. If you have blonde hair and struggle with brassiness, this shampoo is a game-changer. It tones beautifully without drying out my hair, leaving it soft, shiny, and salon-fresh every time I use it. The pigment is rich but not overpowering, and I noticed a visible difference after just one wash. Plus, the scent is lovely—clean and subtle, not overwhelming like some others. It’s become a staple in my routine, and I genuinely look forward to using it. If you’re blonde and looking for something that actually works, this is the one. Total holy grail status.

I’ve tried several purple shampoos and this one is not drying and provides the BEST brightness and shine to my blonde highlights. Removes the yellow and brassiness so well! Once a week I use a clarifying shampoo first, then I use this and leave it on my hair for about 5 minutes. I use this for every other shampoo. It smells so good, too.

I’ve been a fan of amika for a while, and this shampoo is another win in their lineup. If you invest in salon-quality blonde, a good purple shampoo is a must—and this one helps keep brassiness at bay without drying out my hair. The consistency is rich and creamy, and the scent is lovely—fresh without being too strong or perfumey. One thing to note: it will stain anything it drips on, especially shower curtains or porous surfaces, so rinse thoroughly after using. That aside, it delivers great toning results and helps extend the life of my color between salon visits. A little goes a long way, and paired with the matching conditioner, it really keeps blonde hair looking fresh and cool-toned. Would’ve been five stars if it weren’t for the staining risk, but otherwise, it’s a strong performer.

The best purple shampoo I’ve used yet. Very nourishing and quick depositing.

love this product!

Works great to prevent brassiness. Will definitely buy again.
