Amika Bust Your Brass Cool Blonde Strength Repair Conditioner 275ml — purple toning, bond-fortifying for color-treated hair

Amika Bust Your Brass Cool Blonde Strength Repair Conditioner is a purple-toned, bond-fortifying conditioner that neutralizes brassy yellow tones while strengthening and hydrating blonde hair.

Formulated for color-treated and naturally light hair, this 275ml conditioner combines ultra-violet pigments, quinoa protein, plant butters, and a bond-reinforcing technology to refresh cool tones and improve hair resilience. When used as a system with the matching shampoo, lab testing showed hair can be 2.2x stronger with 55% less breakage, making it a practical pick for maintaining salon-fresh blonde between appointments.

How does this conditioner remove brassiness without drying my hair?

The product uses violet pigments to neutralize warm, yellow tones on the hair shaft while creamy emollients restore moisture. Instead of stripping, the formula deposits color-correcting pigments and simultaneously replenishes hydration with plant butters and conditioning agents.

• Ultra-violet pigments counteract yellow and orange hues
• Plant butters (rich emollients) restore softness and shine
• Balanced conditioning base avoids over-drying

Will it help reduce breakage and make hair stronger?

This conditioner contains a bond-fortifying technology plus quinoa protein that support the hair structure and help minimize future breakage when used regularly. Independent lab testing of the combined shampoo + conditioner system reported measurable improvements in strength and reduced breakage.

• Bond fortifying technology reinforces weakened areas
• Quinoa protein helps rebuild and support the cuticle
• Clinical testing: 2.2x stronger hair and 55% less breakage as a system*

How should I use it in my blonde-care routine?

Apply to freshly shampooed, towel-dried hair focusing on mid-lengths to ends and leave on for 1–3 minutes to let violet pigments work. Rinse thoroughly, and for best results use alongside the matching Bust Your Brass shampoo as part of a weekly or as-needed toning routine.

• Use after cleansing with a purple or gentle shampoo
• Leave on for short durations for light toning; longer for stronger correction
• Pair with the Amika Bust Your Brass shampoo for system results

Is this safe for color-treated and fragile blondes?

Yes — the formula is designed for color-treated, highlighted, or naturally light hair that needs toning and strengthening. It focuses on neutralizing unwanted warmth while adding moisture and support without harsh sulfates or unnecessary stripping agents.

• Suitable for highlighted, balayaged, and all blonde tones
• Designed to complement color treatments, not remove color
• Gentle conditioning base supports fragile lengths

Who is this for: Amika Bust Your Brass Cool Blonde Strength Repair Conditioner is ideal for anyone with blonde, silver, or lightened hair who wants to reduce brassy tones and improve hair resilience. It suits color-treated clients seeking a toning conditioner that also hydrates and bolsters weak strands; use it periodically or as part of a regular blonde maintenance routine to refresh cool tones and protect hair between salon visits.
