COOL BRUNETTE: A sulphate-free blue toning mask for brunettes, made for salon-lightened and naturally dark hair. It deep conditions while it tones, so brown hair comes out cooler and softer. BLUE PIGMENT: Blue sits opposite orange on the colour wheel, so blue pigment cancels unwanted copper, red and brassy tones. Worked through the mid-lengths and ends, it tones while it deep conditions. TONE DARK HAIR: Apply to towel-dried hair through the mid-lengths and ends, leave for three to five minutes, then rinse thoroughly. Use after Osmo Super Cool Blue Shampoo, or on its own as a weekly treatment. ASH BROWN RESULTS: A blue hair mask and toner for brown hair, taking brunette, bronde and highlighted shades towards a cool ash brown. Not a dye - no ammonia, no peroxide, and it fades gently with washing. MADE IN THE UK & CRUELTY FREE: Salon-quality formulas made in the UK. We don't, never have, and never will, test on animals.
