Unwanted warm tones in my freshly coloured hair drive me around the bend and back again, particularly when they take on a red/orange hue.
Copper tones are great if that's what you were looking for, not so much if you want cool shades.
I'm not the only one either as online searches regarding 'blue shampoo for brunettes' have increased by 70 percent.
However, the hair gods at Redken have come up with the ultimate solution - a shampoo and conditioner aimed at banishing those brassy tones.
Meet Redken Colour Extend Brownlights.
"Through the use of blue and green tones, color depositing toning hair care immediately eliminates the appearance of brassiness and unwanted warmer tones".
And wait for how quickly it takes hold - "in just five minutes, hair will have enhanced colour dimensions that provide cool results".
Ideal, really.
