Amika Bust Your Brass Cool Blonde Strength Repair Shampoo 275ml — violet toning & bond‑fortifying

Amika Bust Your Brass Cool Blonde Strength Repair Shampoo is an ultra-violet cleansing shampoo that tones yellow brassiness while strengthening and hydrating dry, damaged blonde hair.

This professional-strength 275ml shampoo combines violet pigments with bond-fortifying technology, quinoa protein and plant butters to gently remove unwanted warm tones and support strand resilience. Formulated for color-treated and lightened hair, it works best as part of the Bust Your Brass system to reduce breakage and restore a cooler blonde tone without over-drying.

How does this shampoo neutralize brassy tones?

The formula uses ultra-violet pigments that counteract yellow and orange undertones when massaged through wet hair. Regular use evens out warm highlights and helps maintain a cooler, refreshed blonde between salon visits.

• Violet pigments deposit color-correcting tones
• Gentle surfactants lift grime without stripping color
• Works progressively with repeated washes for visible toning

Will it damage or dry out my bleached hair?

Instead of stripping moisture, this shampoo includes plant butters and quinoa protein to hydrate and reinforce fragile strands. It’s designed to reduce the appearance of breakage when used alongside the matching conditioner, improving manageability and softness.

• Quinoa protein helps rebuild and support the hair fiber
• Plant butters add conditioning and smoothness
• Bond-fortifying technology assists in minimizing future breakage

How often should I use the Bust Your Brass shampoo?

Frequency depends on your brass level and hair porosity; many users alternate with a regular gentle shampoo or use 1–3 times weekly for toning. If your hair is very porous or sensitized, start with less frequent use and monitor tone and moisture.

• Use weekly for light toning and maintenance
• Increase to 2–3 times for stronger brass correction
• Pair with Amika conditioner for best anti-breakage performance

What results can I expect and how was it tested?

When used as a shampoo + conditioner system, independent testing reported improved strength and reduced breakage versus untreated hair. Results vary by hair type and color history, but you can expect cooler tone, better hydration, and increased elasticity with consistent use.

• Clinically tested as part of a system for improved strand strength
• Formulated for color-treated, lightened, and natural blondes
• Designed to support salon color between appointments

Who is this for? If you have highlighted, bleached, or naturally blonde hair and want to neutralize unwanted warmth while strengthening thirsty strands, Amika Bust Your Brass Cool Blonde Strength Repair Shampoo is tailored to that need. It’s ideal for people seeking a conditioner-compatible purple shampoo that tones brassiness without overdrying, and for anyone looking to protect fragile hair from breakage between salon services.
