Amika Bust Your Brass Toning + Strength Repair Mask 250ml — Neutralizes Brassiness, Strengthening Hydration

amika Bust Your Brass Toning + Strength Repair Mask is a 250ml intensive hair treatment that neutralizes brassiness while reinforcing and moisturizing fragile blonde, silver, and gray strands.

Formulated to balance unwanted warm tones and restore resilience, this rich mask combines multiple plant butters and targeted reparative ingredients to hydrate, detangle, and improve hair strength after a single use. Clinically tested results highlight brighter, more conditioned hair with reduced breakage, making it a go-to treatment for color-treated and naturally light hair types seeking cooler tone and improved integrity.

How does this mask reduce brassiness without overdrying hair?

The formula deposits toning pigments that counteract yellow and orange undertones while a blend of plant butters and humectants seals in moisture. Instead of stripping the shaft, it balances tone and replenishes softness for a sleek, luminous finish.

• Toning pigments neutralize warm hues for an icy blonde or neutral silver look
• Three plant butters restore moisture to dry, porous strands
• Lightweight conditioning agents prevent dullness and avoid heaviness

What repair and strengthening benefits can I expect after one use?

Clinical testing shows noticeable conditioning and strength improvements after a single application: hair appears smoother, feels more manageable, and resists breakage better. The mask targets weakened areas to reduce snap and split ends over continued use.

• Significantly increased conditioning for easier detangling
• Improved tensile strength to minimize breakage from styling
• Enhanced surface smoothness for shinier-looking strands

How should I use the mask for best results?

Apply to clean, towel-dried hair focusing on mid-lengths to ends, leave on according to desired toning intensity, then rinse thoroughly. Use weekly or as needed—longer leave times intensify the toning effect but monitor results to avoid over-toning.

• Use after shampooing on damp hair for even distribution
• Leave 3–10 minutes for gentle toning; extend slightly for stronger correction
• Rinse fully and style as usual; adjust frequency based on brass level

Will this work on all types of lightened or naturally gray hair?

Yes—formulated to suit color-treated blondes, highlighted hair, silver tones, and natural gray. The mask addresses both color correction and hydration, making it appropriate for multiple light hair conditions while being mindful of fragility.

• Safe for chemically lightened and naturally light shades
• Helps maintain salon color between appointments
• Supports moisture balance for coarse, fine, or porous textures

Who is this for? If you have lightened, highlighted, silver, or gray hair and want to neutralize brassy tones while repairing and hydrating stressed strands, this 250ml amika mask is formulated for you. Ideal for people who regularly color or bleach their hair and anyone seeking a salon-grade at-home treatment to improve tone, manageability, and resilience.
