amika Bust Your Brass Cool Blonde Repair Conditioner

Keep blonde looking cooler, brighter and stronger with amika Bust Your Brass Cool Blonde Strength Repair Conditioner, an ultra-violet toning conditioner designed to neutralize unwanted yellow and brassy tones while hydrating and strengthening the hair. Ultra-violet pigments work through colour theory to counteract yellow warmth in blonde, silver and grey hair, helping maintain a cooler, more balanced tone between salon visits. amika's bond-fortifying technology targets bonds in the hair that are especially vulnerable to breakage from chemical treatments, heat and environmental stressors, while hydrolyzed quinoa protein provides amino acid-rich conditioning support for damaged strands. A nourishing blend of mango butter, shea butter and borage seed oil helps replenish softness and improve manageability, while glycerin and aloe provide additional moisture support. Sea buckthorn oil, amika's signature superfruit ingredient, provides fatty acids and antioxidant compounds that support softness, shine and conditioning. Smoothing silicones help reduce friction, improve manageability and leave lightened hair feeling softer and more polished. When used as part of the Bust Your Brass system, the formula is clinically tested to deliver 2.2× stronger hair with 55% less breakage after one use, while toning, hydrating and strengthening the strands.

How to Use + Best For

After shampooing, massage amika Bust Your Brass Cool Blonde Strength Repair Conditioner through the mid-lengths and ends, leave on for 2–3 minutes, then rinse thoroughly. It is best for blonde, highlighted, balayage, silver and grey hair experiencing unwanted yellow or brassy tones and can be used across straight, wavy, curly and coily textures. Its combination of proteins, plant butters and conditioning ingredients can be particularly beneficial for medium-to-high porosity or chemically lightened hair, while fine or low-porosity hair may prefer a lighter application or less frequent use depending on how the hair responds. Because violet toning products deposit cool pigment, frequency should be adjusted according to your current tone—use more often when brassiness begins to appear and scale back if your blonde starts looking overly cool or violet. For textured blonde hair needing additional moisture, amika recommends incorporating the Bust Your Brass Toning + Strength Repair Mask in place of conditioner as needed.

Take Khair Tip: Purple conditioner isn't meant to make hair lighter—it visually neutralizes unwanted yellow tones, so customize how often you use it based on your blonde rather than automatically using it every wash.
