Made for people with lightened, blonde, or grey hair who want ongoing brass and yellow-tone control built into their regular conditioning step rather than a once-a-week treatment. Any experience level, consumer at-home use — it's a maintenance product meant for routine use, not a corrective one-off treatment like the So Silver mask in the same line.

The case for this over the toning mask in the same line is convenience: it replaces a regular conditioner rather than adding a separate step, so brass correction happens automatically every time hair is washed instead of needing a scheduled treatment. That makes it a better fit for maintaining an already-toned colour day to day, while the mask is better suited to correcting more noticeable brassiness or giving a stronger reset.

After shampooing, apply a small amount from mid-lengths to ends, avoiding the scalp and eyes.

Leave on briefly, then rinse thoroughly.

Use with each wash for consistent colour maintenance. If the product contacts eyes, rinse immediately and thoroughly with water.

Pros

• Combines toning and conditioning so brass control doesn't require a separate treatment step
• Silicone-based conditioning agent (amodimethicone) gives more slip and detangling benefit than a plain toning mask
• Built for routine, every-wash use rather than a treatment that has to be timed and monitored

Cons

• As a conditioner, its toning effect is generally lighter than a longer-contact treatment like the So Silver mask
• Contains fragrance and fragrance-related compounds (limonene, linalool)
• Ingredient sourcing shows inconsistency across databases — an older formulation reference exists alongside the current one, so anyone with a specific sensitivity should check the physical label before use
