The brunette's answer to brassiness. Osmo Super Cool Zero Orange Mask is an intensely hydrating, sulphate-free treatment made specifically for salon-lightened brunette to dark hair. Where purple toners tackle yellow in blondes, this one uses super-blue pigments to neutralise the orange, red and copper warmth that dark hair tends to pull when it's lightened, helping restore cool colour balance while conditioning at the same time. The result is deeper tones that look cleaner, cooler and salon-fresh.

What it does for your hair

Lightened dark hair fades warm, showing orange and red reflections, and blue pigment is the shade directly opposite those on the colour wheel, so it helps cancel them out for a cooler, more balanced result. As it tones, the hydrating, sulphate-free formula helps replenish moisture in hair that can feel dry after lightening, so it feels softer and looks glossier and more radiant. A simple way to keep warmth in check and condition topped up in one step.

How to use it

Apply to clean, towel-dried hair and work evenly through the lengths and ends. Leave on to tone and condition, adjusting the time to how much toning you want (start with less on more porous or lighter areas to avoid over-toning), then rinse thoroughly. We'd suggest a strand test before use, and wearing gloves, as the pigment can stain.

Who it's for

This one's for anyone with salon-lightened brunette to dark hair, balayage, highlights or an all-over lift, who wants to keep orange and brassy warmth at bay while caring for lightened lengths. We've been perfecting colour, blow-dries and styling for clients in Codsall for years, so we know keeping cool brunettes looking clean and balanced comes down to the right blue toning treatment at home.

Strand test before use. This is a pigmented toning mask and may stain skin, hands, towels, clothing and surfaces, so wear gloves and avoid contact with clothing, and it may leave a blue cast if left on too long or used on very porous hair. Avoid contact with the eyes and rinse immediately if contact occurs. Keep out of reach of children.
