Amika Bust Your Brass Toning + Strength Repair Mask 250ml — neutralizes brass, restores strength & shine

Amika Bust Your Brass Toning + Strength Repair Mask is an intensive 250ml treatment that neutralizes brassiness while restoring moisture, strength and shine to blonde, silver, and gray hair.

This salon-grade mask combines toning pigments with reparative ingredients to refresh faded color, reduce yellowing, and fortify weakened strands after chemical services, heat styling, or seasonal damage. Clinically proven to improve conditioning, increase strength, and reduce breakage after a single use, the formula uses a blend of plant butters and targeted actives to deliver visible results without weighing hair down. It’s formulated for color-treated and naturally light hair seeking a brighter, healthier finish.

How does this mask remove unwanted brass and yellow tones?

The mask deposits cool-toning pigments that neutralize warm, brassy tones while conditioning the hair to prevent over-drying. It balances color quickly and evenly for icy blondes, platinum, silver, and gray shades without leaving a violet residue.

• Blue-violet pigments specifically counteract yellow/orange undertones
• Deep-conditioning base ensures even pigment distribution
• Safe for repeated use as a weekly refreshing treatment

What repair and strengthening benefits will I see after using it?

Formulated to rebuild resilience, the mask targets porous, damaged cuticles to improve elasticity and reduce snapping. In clinical testing it showed significant increases in conditioning and measurable strength gains after one application.

• Strengthens hair fibers to lower breakage during styling
• Three plant butters deliver rich moisture to dry, brittle ends
• Improves manageability and reduces frizz for smoother styling

How should I use the 250ml mask for best results?

Apply to clean, towel-dried hair, focusing on mid-lengths to ends; leave on according to desired toning intensity and rinse thoroughly. Use as a weekly deep treatment or more often for stubborn brassiness, adjusting leave time based on hair porosity and color level.

• Shampoo, towel-dry, apply evenly through hair
• Leave 5–15 minutes for maintenance; longer for deeper toning
• Rinse well and style as usual; use 1–2 times weekly

Will this mask work on all light hair types and color levels?

Yes — it’s designed for natural blondes, bleached hair, platinum, silver, and gray tones. The intensity of toning changes with hair porosity and starting shade, so results vary; lower porosity hair may need longer processing than highly porous, damaged strands.

• Effective on natural and color-treated blonde shades
• Safe for silver and gray to reduce yellowing
• Adjust application time based on hair condition and desired tone

Who is this for? Amika Bust Your Brass Toning + Strength Repair Mask is ideal for anyone with light-colored hair—bleached, highlighted, platinum, silver or gray—who wants to eliminate brassiness while rebuilding strength and moisture. It’s suited to salon clients and at-home color maintainers who need a potent, easy-to-use mask that delivers visible brightening and repair without flattening natural movement. If your hair is chemically treated, porous, or showing breakage, this 250ml treatment offers both corrective toning and nourishing care to help hair look and feel healthier between professional services.
