A purple toning shampoo with bond repair actives — neutralises brassiness in blonde and highlighted hair while strengthening the hair shaft from within.
The Moda Team Review
Bust Your Brass does two things at once: it tones and it repairs. The purple pigment neutralises yellow and orange tones that develop in blonde and highlighted hair between salon visits, while The Kure bond repair actives address the structural damage that lightening causes. Most toning shampoos only do one. This one does both — and it's why it works particularly well for clients whose hair is both brassy and damaged, which is most bleached clients.
Why Moda Carries This
Amika was founded in Brooklyn in 2007 and is B-Corp certified, vegan, and cruelty-free. We carry it because our clients ask for it by name — and because it earns its place on performance. The brand has a fun, young energy and a more accessible price point than our core professional lines, without sacrificing results. Perk Up is the dry shampoo we recommend more than any other. The treatment masks — Soulfood, Hydro Rush, The Kure Intense — consistently over-deliver. B-Corp certification aligns with the values we hold as a team and as parents.
Key Ingredients
-
Purple Pigment: Colour theory — purple neutralises yellow and orange, keeping blonde cool and bright between salon visits.
-
Bond Repair Complex: The same Kure actives that rebuild the disulphide bonds weakened by bleach and colour processing.
Moda Pro Tip
Contact time controls the result. 1–2 minutes for subtle toning. 3–5 minutes for a visibly cooler result. Leave longer than 5 minutes only if hair is very yellow or you specifically want an icy finish.
How To Use
- Apply to wet hair 1–2x per week.
- Leave 1–5 minutes depending on desired toning level.
- Rinse and follow with Bust Your Brass Conditioner.
