Redken Blondage: Purple Shampoo for Brassy Blondes

By Codie Hair, Owner, UKIYO Wānaka. Updated November 2026.

Color Extend Blondage is Redken's purple range for blonde and highlighted hair that's turning warm or brassy. Violet pigments cancel the yellow, and citric acid helps strengthen lightened hair. Most blondes only need it once or twice a week.

What does Redken Color Extend Blondage do?

The shampoo, conditioner and mask all deposit pure violet pigment, which neutralises yellow and brassy tones so blonde looks cooler and brighter. They're made with citric acid to help strengthen hair that's been lightened.

Who is Redken Color Extend Blondage for?

Blondes, highlights and balayage that go warm between toners. If your blonde is very pale or icy, use it less often and for less time, or it can leave a lilac tint. If your hair is breaking from lightening, pair it with Acidic Bonding Concentrate.

How to use the Color Extend Blondage routine, in order

1. Once or twice a week: Color Extend Blondage Shampoo 300ml. Lather, leave on for one to three minutes (less on very light hair), rinse.
2. Condition: Color Extend Blondage Conditioner 300ml. Use after the purple shampoo, or on its own for a lighter tone boost.
3. When brass is strong: Color Extend Blondage Mask 250ml. The mask gives the strongest toning hit. Watch the time on pale blonde.
4. Other washes: Acidic Color Gloss Shampoo 300ml. Use a colour-care shampoo such as Acidic Color Gloss or Color Extend Magnetics in between.

Which Color Extend Blondage product should you start with?

• Start here: the shampoo, once a week.
• Pale or icy blonde: the conditioner alone is often enough.
• Very brassy: shampoo plus the mask, once a week.
• Lightened and fragile: Blondage once a week, Acidic Bonding Concentrate the rest of the time.

Redken Color Extend Blondage questions we get asked

How often should I use Redken Blondage?

Once or twice a week for most blondes. Use a colour-care shampoo for your other washes.

Can purple shampoo turn my hair purple?

On very light or porous blonde it can leave a lilac tint if left on too long. Rinse sooner, use it less often, or use the conditioner on its own. It washes out.

Does Blondage work on brown hair with highlights?

Yes, on the lightened pieces. It won't change the darker hair.

Will it fix orange tones?

Purple cancels yellow. Orange brass on darker blonde needs a blue-based toner, which is a salon job.
