Amika Bust Your Brass Cool Blonde Strength Repair Shampoo 33.8 fl oz. 1L

What It Is
A violet-pigmented shampoo that neutralizes brassy tones while strengthening and hydrating for softer, brighter, more manageable blonde, silver, or gray hair.

What It Does
Take blondes (and beyond) to their brightest. This ultra-violet shampoo works overtime in the bowl or at home—toning down unwanted yellow hues while infusing strands with hydration and strength. Powered by bond fortifying technology, nutrient-rich plant butters, quinoa protein, and ultra-violet pigments, it restores softness, shine, and vibrancy to dry, damaged hair while enhancing cool tones.
