Amika Bust Your Brass Cool Blonde Strength Repair Shampoo is a violet-pigmented toning shampoo for blonde, silver, and gray hair that's also formulated to strengthen strands, combining color-correcting violet dye with a bond-supporting conditioning base rather than acting as a tone-only purple shampoo.

The formula uses amika's bond-fortifying technology alongside quinoa-derived protein and a blend of mango, borage, avocado, and shea plant oils/butters, paired with violet pigments that counteract yellow and brassy undertones. It's free of traditional sulfates, parabens, phthalates, mineral oil, and petrolatum. Used as a system with its matching conditioner, the brand's clinical testing reports 2.2x stronger hair and 55% less breakage after one use, and the system is tested as safe for color-treated hair.

How to Use

Lather and massage through wet hair, from roots to ends
Rinse thoroughly
Adjust frequency to your tone: use it more often if brassiness starts showing through, or cut back for a week or two if hair starts looking too cool or slightly violet

For anyone with blonde, silver, gray, or lightened/highlighted hair that develops warm, brassy, or yellow undertones between salon visits, and who also wants a shampoo that addresses strand strength rather than tone alone. It isn't intended for hair without cool-toning needs — on darker, non-lightened hair the violet pigment has little visible benefit and isn't the point of the product.

Most purple shampoos only address brassiness; this one pairs that violet color-correction with amika's bond-fortifying technology and plant-derived proteins and oils aimed at strand strength, so a single wash step is working on both tone and hair condition. The brand's own clinical testing behind the strength claims, and its use of quinoa protein and plant butters instead of heavier silicones, are the main things separating it from a basic toning shampoo.

Lather and massage through wet hair, working from roots to ends
Rinse thoroughly
For best strengthening results, follow with amika's matching conditioner as a system
Tune frequency to your tone: increase use if brassiness starts to show, or scale back for a week or two if hair starts looking too cool/violet

It combines brass-correcting violet pigment with a plant-oil and protein conditioning base, so it's doing tone correction and conditioning in the same step rather than requiring a separate treatment.

Violet pigment can leave an overly cool, ashy, or faint purple cast if used too frequently or left on too long, especially on very light or porous ends
The tested 2.2x stronger / 55% less breakage figures are based on using it as a full system with the matching conditioner, so a shampoo-only routine may not match those numbers
Not useful as a toning product on hair without lightened or gray/silver tones
