Amika Bust Your Brass Cool Blonde Strength Repair Shampoo 275ml — Violet-Toning, Strengthening

amika Bust Your Brass Cool Blonde Strength Repair Shampoo is a violet-toned repairing shampoo that tones brassy hues while reinforcing weakened blonde hair.

If you want to keep blonde, silver, or highlighted hair bright without sacrificing strength, this shampoo combines violet pigments with bond-supporting ingredients to both neutralize warmth and help rebuild fragile strands. Formulated with quinoa protein, plant butters, and bond-fortifying technology, it targets yellowing and dryness from color processing, environmental stress, and mechanical damage. The result is cleaner, cooler-looking blonde that feels more resilient after regular use as part of the matching system.

How does this shampoo reduce brassy or yellow tones?

Violet pigments counteract warm yellow and orange tones that make blonde hair look dull. The color-correcting molecules deposit subtle purple tones on the hair's surface while the gentle surfactants remove buildup that can exaggerate brassiness.

• Ultra-violet pigments neutralize yellow and brassy hues.
• Removes mineral and styling product buildup that dulls color.
• Leaves a cooler, clearer blonde tone with controlled application.

Will it strengthen and help prevent breakage?

This shampoo contains bond-fortifying technology and quinoa protein to support weakened hair fibers. It works to reinforce strands and improve elasticity when used regularly, especially alongside the Amika conditioner designed for the same system.

• Quinoa protein helps rebuild the hair’s internal structure.
• Bond-fortifying technology supports damaged linkages in the fiber.
• Plant butters add moisture to reduce brittleness and snap.

How should I use it for best results?

Use a small amount on wet hair, lather, and leave for 1–3 minutes depending on how much toning you need, then rinse thoroughly. For optimal strength and color results, use in combination with the matching conditioner and limit heat styling and aggressive mechanical stress.

• Apply to wet hair, lather, and wait 1–3 minutes for toning.
• Rinse completely to avoid over-depositing pigment.
• Pair with the matching conditioner to reduce breakage and boost hydration.

Is it suitable for all blonde shades and frequency of use?

It works on cool, warm, and platinum blondes as well as highlighted or silver hair; adjust frequency based on desired toning. Those with very light platinum hair should monitor use to prevent over-toning, while darker blondes may use more often to maintain cool results.

• Safe for color-treated and highlighted blonde shades.
• Use weekly or as needed—less for subtle toning, more for stronger correction.
• Monitor results and reduce contact time for pale platinum shades.

Who is this for? This shampoo is intended for people with blonde, highlighted, or grey hair who want to neutralize unwanted yellow/brassy tones while improving hair strength. It’s especially helpful for anyone with chemically processed, heat-styled, or environmentally stressed hair seeking a combined toning and repair step within their routine. For best outcomes, integrate it with the companion conditioner and follow usage recommendations based on your hair’s lightness and condition.
